The PsbI protein is previously named the 4.8 kda protein and is encoded by plastid. PsbI is a common component of PSII and is highly conserved (e.g. 71% amino acid agreement between Arabidopsis and Synechocystis 6803 proteins). The protein contains 36-38 amino acids in most species and has a molecular weight between 4.1-4.5 kDa. Synonyms: PSII-I, PSII 4.8 kDa protein
