psbA — Lactuca sativa

Summary

psbA (LSAT_V11C800443670) on chromosome 8 of garden lettuce (Lactuca sativa) encodes a protein belonging to the Photo_RC_L/M and Photo_II_D1/D2_sf domain families and possesses oxidoreductase activity acting on diphenols, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding. It is localised to the photosystem II complex in 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 linked to chlorophyll content. Related genes in other species connect the family to the enzyme class 1.10.3.9.
