Zea mays Asp-Based PTP/PGP
※ PGP family introduction PGP, also known as AUM, belongs to a family of phosphatase which uses an Asp nucleophile for catalysis. PGP/AUM is the closest paralog of chronophin. Interestingly, PGP/AUM acts as a tyrosine phosphatase, whereas chronophin dephosphorylates serine/threonine-phosphorylated proteins (1). Prentki, et al., describe that a previously known phosphoglycolate phosphatase (PGP) with an uncertain function in mammalian cells acts as a specific G3PP and plays a pivotal role in the regulation of glucose and lipid metabolism and signaling, as well as in the response to metabolic stress (2). Notably, PGP/AUM is a widely conserved metabolite repair enzyme in mammals which eliminates 4-P-erythronate, a side product of GAPDH (3). Reference
