PSAB_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: PSAB_ARATH
• UniProt AC: P56767
• Protein Name: Photosystem I P700 chlorophyll a apoprotein A2 {ECO:0000255|HAMAP-Rule:MF_00482}
• Gene Name: psaB {ECO:0000255|HAMAP-Rule:MF_00482}
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 734
• Subcellular Localization: Plastid, chloroplast thylakoid membrane ; Multi-pass membrane protein .
• Protein Description: PsaA and PsaB bind P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1 and FX. PSI is a plastocyanin-ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized acceptors A0, A1, FX, FA and FB in turn. Oxidized P700 is reduced on the lumenal side of the thylakoid membrane by plastocyanin..
