Family relationships

Description

Photosystem I is a membrane complex found in the chloroplasts of plants and cyanobacteria. It uses light energy to transfer electrons from plastocyanin to ferredoxin [PMID: 3333014]. The core proteins of photosystem I are PsaA and PsaB, homologous integral membrane proteins that form a heterodimer that binds the electron-donating chlorophyll dimer P700, as well as chlorophyll, phylloquinone, and 4FE-4S electron acceptors [PMID: 3333014].

This entry represents PsaB.
