Protein: Phytyl ester synthase 1, chloroplastic (EC 2.3.1.-) (Q9ZVN2)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Acyltransferase involved in fatty acid phytyl ester synthesis in chloroplasts, a process required for the maintenance of the photosynthetic membrane integrity during abiotic stress and senescence. Exhibits phytyl ester synthesis and diacylglycerol acyltransferase activities with broad substrate specificities, and can employ acyl-CoAs, acyl carrier proteins, and galactolipids as acyl donors.
Subcellular location: Plastid, chloroplast, plastoglobule {ECO:0000269|PubMed:16461379, ECO:0000269|PubMed:22274653, ECO:0000269|PubMed:22623494}.
