Function

function

Found at the monomer-monomer interface of the photosystem II (PS II) dimer, plays a role in assembly and dimerization of PSII. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H2O, generating a proton gradient subsequently used for ATP formation.

Phenotypes & Variants

Disruption phenotype

Decreased photoautotrophic growth. Decreased assembly of PSII monomers and dimers, increased levels of the CP43-less intermediate, plus an altered dimeric form. Double psbM-psbT mutants do not assemble PSII dimers. Cells are light sensitive and rapidly photoinactivated; recovery requires protein synthesis and light.
