>PF06596 PsbX: Photosystem II reaction centre X protein (PsbX); InterPro: IPR009518 Oxygenic photosynthesis uses two multi-subunit photosystems (I and II) located in the cell membranes of cyanobacteria and in the thylakoid membranes of chloroplasts in plants and algae
Photosystem II (PSII) has a P680 reaction centre containing chlorophyll 'a' that uses light energy to carry out the oxidation (splitting) of water molecules, and to produce ATP via a proton pump. Photosystem I (PSI) has a P700 reaction centre containing chlorophyll that takes the electron and associated hydrogen donated from PSII to reduce NADP+ to NADPH. Both ATP and NADPH are subsequently used in the light-independent reactions to convert carbon dioxide to glucose using the hydrogen atom extracted from water by PSII, releasing oxygen as a by-product. PSII is a multisubunit protein-pigment complex containing polypeptides both intrinsic and extrinsic to the photosynthetic membrane [, ]. Within the core of the complex, the chlorophyll and beta-carotene pigments are mainly bound to the antenna proteins CP43 (PsbC) and CP47 (PsbB), which pass the excitation energy on to the reaction centre proteins D1 (Qb, PsbA) and D2 (Qa, PsbD) that bind all the redox-active cofactors involved in the energy conversion process. The PSII oxygen-evolving complex (OEC) oxidises water to provide protons for use by PSI, and consists of OEE1 (PsbO), OEE2 (PsbP) and OEE3 (PsbQ). The remaining subunits in PSII are of low molecular weight (less than 10 kDa), and are involved in PSII assembly, stabilisation, dimerisation, and photo-protection []. The low molecular weight transmembrane protein PsbX found in PSII is associated with the oxygen-evolving complex. Its expression is light-regulated. PsbX appears to be involved in the regulation of the amount of PSII [], and may be involved in the binding or turnover of quinone molecules at the Qb (PsbA) site [].; GO: 0015979 photosynthesis, 0009523 photosystem II, 0016020 membrane; PDB: 3ARC_x 3A0H_X 3A0B_X 3PRR_X 1S5L_x 4FBY_j 3PRQ_X 3KZI_X 3BZ2_X 3BZ1_X.
