PSBO — Pisum sativum

Summary

PSAT0S3575G0040 (PSBO) in garden pea encodes a PsbO domain-containing protein, which exhibits oxygen-evolving activity and poly(U) binding. This gene is associated with photosystem II stabilization and assembly, nonphotochemical quenching, photosynthesis light reactions, thylakoid membrane organization, de-etiolation, and protein import. The product localizes to the chloroplast photosystem II, the oxygen-evolving complex, and the thylakoid membrane. It is also linked to photochemical quenching. Related genes in other species connect the family to similar photosynthetic processes.
