Photosystem I PsaD (IPR003685)

Short name: PsaD

Family relationships

None.

Description

PsaD is a small, extrinsic polypeptide located on the stromal side (cytoplasmic side in cyanobacteria) of the photosystem I reaction centre complex. It is required for native assembly of PSI reaction clusters and is implicated in the electrostatic binding of ferredoxin within the reaction centre [PMID: 9692933]. PsaD forms a dimer in solution which is bound by PsaE however PsaD is monomeric in its native complexed PSI environment [PMID: 9692933].
