|Abstract ||This family consists of the photosystem I reaction centre subunit IX or PsaJ from various organisms including Synechocystis sp. (strain PCC 6803), Pinus thunbergii (Green pine) and Zea mays (Maize).
PsaJ is a small 4.4kDa, chloroplast encoded, hydrophobic subunit of the photosystem I reaction complex whose function is not yet fully understood . PsaJ can be cross-linked to PsaF and has a single predicted transmembrane domain. It has a proposed role in maintaing PsaF in the correct orientation to allow for fast electron transfer from soluble donor proteins to P700+ .|
