This entry consists of the 23 kDa subunit of oxygen evolving system of photosystem II or PsbP from various plants (where it is encoded by the nuclear genome) and Cyanobacteria (known as CyanoP). The 23 KDa PsbP protein is required for PSII to be fully operational in vivo, it increases the affinity of the water oxidation site for Cl- and provides the conditions required for high affinity binding of Ca2+ [2]. Structure of CyanoP from Synechocystis sp. revealed that it has an alpha-beta-alpha fold containing 10 beta strands organized into two anti-parallel beta-sheets, packed against alpha-helices. This entry covers the first seven beta-stands (beta1-beta7) and the N-terminal alpha-helix [1].
This entry represents the C-terminal of PsbP/CyanoP and PsbP-like proteins (also known as 23 kDa subunit of oxygen evolving system of photosystem II) from plants and Cyanobacteria. The 23 KDa PsbP protein is required for PSII to be fully operational ...

Structure of CyanoP from Synechocystis sp. revealed that it has an alpha-beta-alpha fold containing 10 beta strands organized into two anti-parallel beta-sheets, packed against two alpha-helices. This entry covers the last three beta-stands (beta8-beta9-beta10) and the C-terminal alpha-helix [1,2].
This domain represents the N-terminal of NAD(P)H-quinone oxidoreductase subunit 2 (or subunit B), part of the P-module (pumping) of the photosynthetic complex I from plants and cyanobacteria, which is structurally and functionally related to the resp ...
This domain represents the N-terminal of NAD(P)H-quinone oxidoreductase subunit 2 (or subunit B), part of the P-module (pumping) of the photosynthetic complex I from plants and cyanobacteria, which is structurally and functionally related to the respiratory complex I from mitochondria and bacteria. It is involved in the electron transfer between photosynthetic complex I and photosystem I [1].
Cyclophilin type peptidyl-prolyl cis-trans isomerase/CLD
The peptidyl-prolyl cis-trans isomerases, also known as cyclophilins, share this domain of about 109 amino acids. Cyclophilins have been found in all organisms studied so far and catalyse peptidyl-prolyl isomerisation during which the peptide bond pr ...
The peptidyl-prolyl cis-trans isomerases, also known as cyclophilins, share this domain of about 109 amino acids. Cyclophilins have been found in all organisms studied so far and catalyse peptidyl-prolyl isomerisation during which the peptide bond preceding proline (the peptidyl-prolyl bond) is stabilised in the cis conformation. Mammalian cyclophilin A (CypA) is a major cellular target for the immunosuppressive drug cyclosporin A (CsA). Other roles for cyclophilins may include chaperone and cell signalling function [1].
This family includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. The structure of the domain is an alpha-antiparallel beta sandwich.
