psbA — Lactuca sativa

Summary

LSAT_V11C300125770 (psbA) on chromosome 3 of garden lettuce (Lactuca sativa) encodes the PSII_D1 protein, a core component of photosystem II. The gene product possesses oxidoreductase activity acting on diphenols and related substances with oxygen as acceptor, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding. It is associated with photosynthetic electron transport in photosystem II, autotrophy, homologous recombination, response to herbicide, and regeneration. The protein localizes to the photosystem II complex and the chloroplast thylakoid membrane. Related genes in other species link the family to the enzyme classification 1.10.3.9. The gene is also associated with chlorophyll content.
