PSAF_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	PSAF_ARATH
UniProt AC	Q9SHE8
Protein Name	Photosystem I reaction center subunit III, chloroplastic
Gene Name	PSAF
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	221
Subcellular Localization	Plastid, chloroplast thylakoid membrane Single-pass membrane protein Lumenal side.
Protein Description	Participates in efficiency of electron transfer from plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria). This plastocyanin-docking protein contributes to the specific association of plastocyanin to PSI..
