PSD — Pisum sativum

Summary

PsPSD (PSAT2G176840) on garden pea chromosome 2LG1 encodes a phosphatidylserine decarboxylase 1 beta chain, an enzyme with phosphatidylserine decarboxylase activity (EC 4.1.1.65) and calcium ion binding. It belongs to the PSD_type1_euk and PS_Dcarbxylase families. The gene is associated with phosphatidylethanolamine biosynthesis, lipid metabolism, and the decarboxylation of phosphatidylserine within phospholipid biosynthesis. It is also associated with cell cycle control, M phase, interkinetic nuclear migration, nuclear movement, secretion, immune and defense responses, cell death, and response to cholesterol. The encoded protein localises to the mitochondrial inner membrane, ER membrane, vacuolar membrane, and mitochondria. Studies of related genes in other species link the family to days to maturity and photochemical quenching.
