PSBA_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: PSBA_ARATH
• UniProt AC: P83755
• Protein Name: Photosystem II protein D1 {ECO:0000255|HAMAP-Rule:MF_01379}
• Gene Name: psbA {ECO:0000255|HAMAP-Rule:MF_01379}
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 353
• Subcellular Localization: Plastid, chloroplast thylakoid membrane ; Multi-pass membrane protein .
• Protein Description: Photosystem II (PSII) is a light-driven water: plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. The D1/D2 (PsbA/PsbA) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors..
