CD Definition:
PsaD; This family consists of PsaD from plants and cyanobacteria. PsaD is an extrinsic polypeptide of photosystem I (PSI) and is required for native assembly of PSI reaction clusters and is implicated in the electrostatic binding of ferredoxin within the reaction centre. PsaD forms a dimer in solution which is bound by PsaE however PsaD is monomeric in its native complexed PSI environment.
