psbA — Lactuca sativa

Summary

psbA (LSAT_V11C500241190) on chromosome 5 of garden lettuce (Lactuca sativa) encodes the PSII_D1 protein, a core component of Photosystem II. The 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 localizes to the chloroplast thylakoid membrane as part of Photosystem II. The gene is associated with photosynthetic electron transport in photosystem II, autotrophy, homologous recombination, response to herbicide, and regeneration. It is also linked to chlorophyll content. Related genes in other species connect the family to the enzyme class 1.10.3.9.
