psbA — Pisum sativum

Summary

PSAT3G186560 (symbol psbA) on garden pea chromosome 3LG5 encodes a protein with the Photo_RC_L/M_CS, D1/D2, Photo_RC_L/M, and Photo_II_D1/D2_sf domains. The product possesses oxidoreductase activity acting on diphenols with oxygen as acceptor, oxygen-evolving activity, chlorophyll binding, electron transfer activity and iron binding. It localises to the photosystem II complex in the chloroplast thylakoid membrane. The gene is associated with photosynthetic electron transport in photosystem II, the electron transport chain, thylakoid membrane organisation, photoprotection, chloroplast movement, plastid gene expression and transcription, carotenoid and flavonoid anabolism, protein synthesis and breakdown, membrane organisation, homeostasis, and response to herbicide. It is also linked to protein content. Related genes in other species connect the family to photosystem II protein D1 and the same core photosynthetic functions.
