The crystal structure of Deg9 reveals a novel octameric-type HtrA protease. International journal

Language：English Publisher：NATURE PUBLISHING GROUP

The high temperature requirement A (HtrA) proteases (also termed Deg proteases) play important roles in diverse organisms by regulating protein quality and quantity. One of the 16 Arabidopsis homologs, Deg9, is located in the nucleus where it modulates cytokinin- and light-mediated signalling via degrading the ARABIDOPSIS RESPONSE REGULATOR 4 (ARR4). To uncover the structural features underlying the proteolytic activity of Deg9, we determined its crystal structure. Unlike the well-established trimeric building block of HtrAs, Deg9 displays a novel octameric structure consisting of two tetrameric rings that have distinct conformations. Based on the structural architecture, we generated several mutant variants of Deg9, determined their structure and tested their proteolytic activity towards ARR4. The results of the structural and biochemical analyses allowed us to propose a model for a novel mechanism of substrate recognition and activity regulation of Deg9. In this model, protease activation of one tetramer is mediated by en-bloc reorientation of the protease domains to open an entrance for the substrate in the opposite (inactive) tetramer. This study provides the structural basis for understanding how the levels of nuclear signal components are regulated by a plant protease.

Oxygenic photosynthesis synthesizes sugars from water and carbon dioxide using light energy from the sun, thereby converts light energy into chemical energy and provides oxygen for aerobic life on the earth. The light-harvesting, electron transfer, and water-splitting reactions of photosynthesis are catalyzed by two large membrane-protein complexes photosystem II (PSII) and photosystem I (PSI). Through high-resolution crystal structural analysis by synchrotron X-rays as well as femtosecond X-ray free electron lasers, the mechanisms of these reactions have become understandable at the atomic level. Here we review the recent progresses in analyzing the structures of PSII and PSI as well as their functional implications.

Photosystem II (PSII) is a membrane-protein complex consisting of 17 trans-membrane subunits and 3 peripheral, extrinsic subunits with a total molecular mass of 350 kDa for a monomer. PSII performs a series of light-induced electron transfer reactions, leading to the conversion of light energy into biologically useful chemical energy, coupled with this is the splitting of water and generation of molecular oxygen. Both the chemical energy converted and molecular oxygen generated by PSII are indispensible for sustaining life on the earth; thus PSII is an extremely important protein complex. We have succeeded in crystallizing the PSII complex at a resolution of 1.9 Å, and analyzed its structure. Here we describe the structure of PSII, in particular the Mn₄CaO₅-cluster, which is the catalytic center of water-splitting, analyzed at the atomic resolution. Based on these, we discuss the possible mechanisms of light-induced water-splitting and its implications in artificial photosynthesis.<br>

The unfolding of 23kD (P23k) protein isolated from spinach photosystem II particle was studied by high pressure and fluorescence spectroscopy. The thermal equilibrium study indicated that the protein could be totally unfolded by 180 or 160 MPa at 20 degreesC and 3 degreesC, respectively. The standard free energy and standard volume change of the protein for unfolding at 20 degreesC is 23.45 kJ/mol and - 150.3 ml/mol, respectively. Kinetics study indicated that at 20 degreesC the activation volume for unfolding, Delta V-u(double dagger), was negative ( - 66.2 ml/mol), meanwhile the activation volume for folding, Delta V-f(double dagger), was positive (84.1 ml/mol). The rate constants for folding and unfolding (K-0f, K-0u) were 1.87 s(-1) and 1.3 x 10(-4) s(-1), respectively, these results provide some clues to explain why the protein is so sensitive to pressure.

Low pH-Induced Dissociation of Three Extrinsic Proteins from O_2-Evolving Photosystem II :

Shen Jian-Ren, Inoue Yorinao

Plant and cell physiology 32 ( 3 ) 453 - 457 1991

Language：English Publisher：Japanese Society of Plant Physiologists

Three extrinsic proteins involved in oxygen evolution reversibly dissociated from Photo-system II (PS II) membranes at acidic pHS showing distinctly different pH dependencies. The pHS for half dissociation of 17, 23 and 33 kDa extrinsic proteins were determined to be 5.0, 4.1 and 3.6, respectively. The half dissociation pHS Of 17 and 23 kDa proteins were much lower than their respective isoelectric points, while that for 33 kDa protein was close to its isoelectric point. It was suggested that protonation of the negatively charged binding domain on membrane proteins causes dissociation of the former two extrinsic proteins, whereas protonation of the extrinsic protein itself is responsible for the dissociation of 33 kDa protein. Based on these, features of low pH-induced dissociation of extrinsic proteins and Mn from PS II were discussed.

A brief treatment at pH 3.0 of Photosystem II (PS II) membranes containing two bound Ca^<2+> from rice resulted in strong suppression of oxygen evolution concomiiant with extraction of one Ca^<2+> and the lost activity was restored on addition of 50 mM Ca^<2+>. However, inactivation of oxygen evolution by low pH-treatment of oxygen-evolving PS II complexes containing only one Ca^<2+> from a rice chlorophyll b-deficient mutant was not associated with extraction of the bound Ca^<2+>, although oxygen evolution was markedly enhanced by the addition of Ca^<2+> to the treated complexes. Thus, the acid-inactivation of oxygen evolution cannot be related to extraction of Ca^<2+>. On the other hand, low pH-treatment was found to share the following common features with NaCl-treatment which also causes a Ca^<2+>-reversible inactivation of oxygen evolution. (1) Exposure of PS II membranes to pH 3.0 resulted in solubilization of the 23 and 17 kDa extrinsic proteins, although the released proteins rebound to the membranes when pH was raised to 6.5. (2) There was an apparent heterogeneity in the binding affinity of Ca^<2+> effective in restoration of the oxygen-evolving activity. (3) Low pH-treated preparations required a higher concentration of Ca^<2+> for the maximum reactivation of oxygen evolution than did NaCl-washed preparations. This was also the case with Sr^<2+>, which stimulated oxygen evolution of both low pH-treated and NaCl-washed PS II membranes to smaller extents. When the extrinsic 23 and 17 kDa proteins had been removed, however, Ca^<2+> concentration dependence of oxygen evolution in low pH-treated membranes became similar to that in NaCl-washed PS 11 preparations and the changes were largely reversed by rebinding of the two proteins. These results strongly suggest that low pH-treatment and NaCl-wash involve similar mechanisms of Ca^<2+>-dependent reactivation.

Oxygen-evolving Photosystem II (PS II) complexes, which were largely deprived of major light-harvesting chlorophyll a/b proteins (LHC II) but still associated with the 33 kDa, 23 kDa and 17 kDa extrinsic proteins related to oxygen evolution, were isolated from spinach oxygen-evolving PS II membranes with a non-ionic detergent, n-heptyl thioglucoside. A minor antenna chlorophyll-protein (CP 29) was present but in reducted amounts. The complexes contained all the constituent subunits of PS II reaction center core complexes, the 47 kDa and 43 kDa chlorophyll-carrying proteins, the D1 and D2 proteins and cytochrome b-559. In addition, three hydrophobic proteins of 29 kDa (CP 29 apoprotein), 20 kDa and 10 kDa were present. The antenna size was 80 chlorophyll a per QA, or 76 chlorophyll a per 4 Mn, and the complexes contained about 1 Ca2+ per PS II. With phenyl- or dichloro-p-benzoquinone as electron acceptor, the complexes showed high rates of oxygen evolution in the absence of exogenously added Ca2+. The activity became, however, strongly Ca2+-dependent when the 23 kDa and 17 kDa proteins, but not the bound Ca2+, had been removed with 1.5 M NaCl. The Ca2+ requirement disappeared on reconstitution of the complexes with the two proteins. The complexes were compared with other oxygen-evolving preparations having different polypeptide compositions and functions of several subunit proteins and Ca2+ in PS II electron transport are discussed. © 1989 Elsevier Science Publishers.

Nearest neighbor relationships among constituent proteins of oxygen-evolving Photosystem II (PS II) membrane preparations from spinach were investigated by means of crosslinking with a cleavable bifunctional crosslinker, dithiobis(succinimidylpropionate) (DSP). (1) Diagonal gel electrophoresis revealed crosslinking between two extrinsic proteins of 17 and 23 kDa, between the extrinsic 33 kDa protein and the 47 kDa chlorophyll-carrying protein and between the 26 and 27 kDa apoproteins of light-harvesting chlorophyll a/b protein. In addition, a product which involved a protein of 29 kDa was detected. (2) Amounts of the extrinsic proteins crosslinked were determined by washing DSP-treated membranes with high concentrations of urea and NaCl, or CaCl2. Neither of the two extrinsic proteins of 17 and 23 kDa was crosslinked with intrinsic membrane proteins, whereas 15 to 20% of the 33 kDa protein was immobilized by treatment with 0.1% DSP. Oxygen evolution became resistant to the urea/NaCl-wash proportionally to the amount of the 33 kDa protein crosslinked, indicating that the 33 kDa protein covalently bound to the 47 kDa protein is still fully functional. (3) The crosslinking of the 33 kDa protein accompanied by parallel increases in the amount of Mn remained unextracted, and the rate of oxygen evolution survived after 30-min treatment of PS IImembranes at pH 9.0. Thus the 33 kDa protein has a protective effect on the Mn cluster at the alkaline pH. In contrast, Mn was mostly extracted with a high concentration of Tris, irrespective of the crosslinking of the 33 kDa protein. © 1989 Elsevier Science Publishers B.V.
