  • Description Photosystem I PsaA

Abstract

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 [ 1 ]. 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 [ 2 ].

This entry represents PsaA.
