PSBO — Pisum sativum

Summary

PSAT2G168600, symbol PSBO, encodes the PsbO protein, a component of the oxygen-evolving complex (OEC) in garden pea (Pisum sativum) on chromosome 2LG1. The product possesses oxygen-evolving activity and poly(U) binding capability. This gene is associated with photosystem II stabilization and assembly, nonphotochemical quenching, membrane and thylakoid membrane organization, photosynthesis light reactions, de-etiolation, and protein import. It is localized to the chloroplast photosystem II, the OEC complex, and the chloroplast thylakoid membrane. PSBO is also linked to photochemical quenching. Related genes in other species, such as OEE1, are linked by sequence similarity.
