psbA — Pisum sativum

Summary

PSAT0S8829G0040, the psbA gene of garden pea (Pisum sativum) on chromosome CAADHX020017397.1, encodes a protein belonging to the 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 is localised to the photosystem II complex and 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, translation elongation and initiation, protein synthesis and breakdown, membrane organisation, carotenoid and flavonoid anabolism, homeostasis, and response to herbicide. It is also linked to protein content. Related genes in other species link the family to oxidoreductase activity (EC 1.10.3.9).
