psbA — Pisum sativum

Summary

PSAT0SS8367G0160, symbol psbA, encodes a product belonging to the D1/D2 and Photo_RC_L/M families in garden pea (Pisum sativum) on chromosome CAADHX020024488.1. 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 localized 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 organization, photoprotection, response to herbicide, chloroplast movement, plastid gene expression and transcription, carotenoid and flavonoid anabolism, protein synthesis and breakdown, translation elongation and initiation, membrane organization, and homeostasis. It is also linked to protein content. Studies of related genes in other species place the family within the PSII_D1 domain and EC 1.10.3.9.
