PSBA — Pisum sativum

Summary

PsPSBA (PSAT0SS8367G0080) on garden pea chromosome CAADHX020024488.1 encodes a protein belonging to the D1/D2, Photo_RC_L/M, and Photo_II_D1/D2_sf domain families. The product exhibits oxidoreductase activity acting on diphenols with oxygen as acceptor, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding. It localises to the chloroplast thylakoid membrane and Photosystem II. The gene is associated with photosynthetic electron transport in Photosystem II, the electron transport chain, photoprotection, thylakoid membrane organisation, plastid gene expression and transcription, carotenoid and flavonoid anabolism, protein synthesis and breakdown, chloroplast movement, membrane organisation, homeostasis, and response to herbicide. It is also linked to protein content. Studies of related genes in other species further connect the family to the PSII_D1 domain and EC 1.10.3.9.
