psbA — Pisum sativum

Summary

PSAT0S6638G0040 (psbA) in garden pea encodes a protein with D1/D2 and Photo_RC_L/M 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 localizes to the photosystem II complex in the chloroplast thylakoid membrane. The gene is associated with photosynthetic electron transport in photosystem II, thylakoid membrane organization, photoprotection, chloroplast movement, plastid gene expression and transcription, translation elongation and initiation, protein synthesis and breakdown, membrane organization, carotenoid and flavonoid anabolism, homeostasis, and response to herbicide. It is also linked to protein content. Studies of related genes in other species connect the family to additional oxidoreductase activity (EC 1.10.3.9).
