Alternative name(s):
LC 7.8
Gene names
Name:apcC
Ordered Locus Names:ssr3383
OrganismSynechocystis sp. (strain PCC 6803 / Kazusa) [Reference proteome] [HAMAP]
Taxonomic identifier1111708 [NCBI]
Taxonomic lineageBacteriaCyanobacteriaOscillatoriophycideaeChroococcalesSynechocystis

Protein attributes

Sequence length67 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Rod linker protein, associated with allophycocyanin. Linker polypeptides determine the state of aggregation and the location of the disk-shaped phycobiliprotein units within the phycobilisome and modulate their spectroscopic properties in order to mediate a directed and optimal energy transfer By similarity.

Subcellular location

Cellular thylakoid membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Note: This protein occurs in the rod, it is associated with allophycocyanin By similarity.

Sequence similarities

Belongs to the phycobilisome linker protein family.

Contains 1 cpcD-like domain.
