psbA — Lactuca sativa

Summary

LSAT_V11C400210490 (psbA) on chromosome 4 of garden lettuce (Lactuca sativa) encodes the PSII_D1 protein, a core component of photosystem II. The gene product exhibits oxidoreductase activity acting on diphenols and related substances as donors with oxygen as acceptor, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding. It is localized to the photosystem II complex within the chloroplast thylakoid membrane. The gene is associated with photosynthetic electron transport in photosystem II, autotrophy, homologous recombination, response to herbicide, and regeneration. It has also been connected to chlorophyll content. Related genes in other species link the family to the enzyme class 1.10.3.9.
