Protein Classification

photosystem II protein K( domain architecture ID 10000052)

photosystem II protein K is one of the components of the core complex of photosystem II (PSII), which is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation

Photosystem II 4 kDa reaction centre component; This family consists of various photosystem II 4 kDa reaction centre components (PsbK) from plant and Cyanobacteria. The photosystem II reaction centre is responsible for catalysing the core photosynthesis reaction the light-induced splitting of water and the consequential release of dioxygen. In C. reinhardtii the psbK product is required for the stable assembly and/or stability of the photosystem II complex.
