General annotation (Comments)

Function

Low-potential cytochrome c that plays a role in the oxygen-evolving complex of photosystem II (PSII). Required for normal function or stabilization of PSII. Extrinsic protein associated with PSII that enhances oxygen evolution. HAMAP MF_01378

Cofactor

Binds 1 heme group covalently per subunit.

Subunit structure

The cyanobacterial oxygen-evolving complex is composed of psbO, psbP, psbQ, psbV and psbU Potential.

Subcellular location

Cellular thylakoid membrane; Peripheral membrane protein; Lumenal side Probable. Note: Associated with photosystem II at the lumenal side of the thylakoid membrane Probable. Ref.1

Disruption phenotype

Cells show decreased but not abolished level of PSII and photoautotrophic growth. Ref.1

Sequence similarities

Belongs to the cytochrome c family. PsbV subfamily.

Sequence caution

The sequence AAA19982.2 differs from that shown. Reason: Erroneous initiation.
