REMARK 6 REMARK 6 IN PLANTS, ALGAE, AND CYANOBACTERIA, PHOTOSYSTEM II (PSII) REMARK 6 CARRIES OUT THE LIGHT-DRIVEN REDUCTION OF PLASTOQUINONE BY REMARK 6 ELECTRONS DERIVED FROM WATER. THE PSII COMPLEX IS LOCATED REMARK 6 IN THE THYLAKOID MEMBRANE (OF THE CHLOROPLAST) AND IS REMARK 6 COMPOSED OF MORE THAN 20 POLYPEPTIDE SUBUNITS. THE D1 AND REMARK 6 D2 PROTEINS CONSTITUTE THE PSII REACTION CENTER AND FORM A REMARK 6 HETERODIMER THAT BINDS THE REDOX COMPONENTS NECESSARY FOR REMARK 6 THE PRIMARY ELECTRON TRANSFER REACTIONS. BOTH THE D1 AND D REMARK 6 PROTEINS CONTAIN FIVE TRANSMEMBRANE ALPHA-HELICES.

REMARK 7 REMARK 7 THE THEORETICAL MODEL INCLUDE RESIDUES 106 - 224 AND 266 - REMARK 7 297 OF THE D1 PROTEIN AND RESIDUES 106 - 224 AND 263 - 294 REMARK 7 OF THE D2 PROTEIN. HELIX A AND SOME EXTRINSIC LOOPS ARE NO REMARK 7 INCLUDED DUE TO LOW SIMILARITY WITH THE TEMPLATE STRUCTURE. REMARK 7 INCLUDED ARE FOUR CHLOROPHYLL A MOLECULES, TWO PHEOPHYTIN A REMARK 7 AND A FE2+ ION. OF THE FOUR CHLOROPHYLLS, TWO ARE BOUND IN REMARK 7 THE CENTER BETWEEN THE D1 AND D2 PROTEINS. THESE REMARK 7 CHLOROPHYLLS CONSTITUTE THE P680 PARALLEL PAIR. THE TWO REMARK 7 OTHER 'ACCESSORY' CHLOROPHYLLS ARE BOUND ONE TO EACH OF THE REMARK 7 D1 AND D2 PROTEINS. NO HYDROGEN ATOMS ARE INCLUDED IN REMARK 7 THIS ENTRY.

REMARK 220 REMARK 220 EXPERIMENTAL DETAILS REMARK 220 EXPERIMENT TYPE : THEORETICAL MODELLING REMARK 220 REMARK 220 REMARK: HOMOLOGY MODELLING BASED ON THE STRUCTURE OF THE REMARK 220 PHOTOSYNTHETIC REACTION CENTER FROM RHODOPSEUDOMONAS REMARK 220 VIRIDIS, PDB ENTRY 1PRC (J.DEISENHOFER,O.EPP,I.SINNING, REMARK 220 H.MICHEL, J.MOL.BIOL. 246, 429, 1995). ONLY THE MOST REMARK 220 SIMILAR PROTEIN REGIONS WERE USED. NON-CONSERVED SIDE- REMARK 220 CHAINS WERE POSITIONED USING A ROTAMER LIBRARY BASED REMARK 220 METHOD (P.TUFFERY,C.ETCHEBEST,S.HAZOUT,R.LAVERY, REMARK 220 J.BIOMOL. STRUCT. DYNAM. 8, 1267, 1991). THE MODEL WAS REMARK 220 ENERGY MINIMIZED USING CHARMM (B.R.BROOKS, REMARK 220 R.E.BRUCCOLERI, B.D.OLAFSON,D.J.STATES,S.SWAMINATHAN, REMARK 220 M.KARPLUS, J. COMP. CHEM. 4, 187, 1983). THE PIGMENT REMARK 220 CONFORMATIONS WERE OPTIMIZED USING EXCITONIC INTERACTION REMARK 220 CALCULATIONS (REFERENCE 1). SIDE CHAINS AND PIGMENT REMARK 220 INTERACTIONS WERE FURTHER OPTIMIZED BY ENERGY REMARK 220 CALCULATIONS USING CHARMM.

REMARK 225 REMARK 225 THEORETICAL MODEL REMARK 225 THE COORDINATES IN THIS ENTRY REPRESENT A MODEL STRUCTURE. REMARK 225 PROTEIN DATA BANK CONVENTIONS REQUIRE THAT CRYST1 AND REMARK 225 SCALE RECORDS BE INCLUDED, BUT THE VALUES ON THESE REMARK 225 RECORDS ARE MEANINGLESS.
