The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout
At the inner mitochondrial (IM) membrane, PTPMT1 (phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1) catalyzes the dephosphorylation of phosphatidylglycerophosphate (PGP) to phosphatidylglycerol (PG). The biochemical properties of human PTPMT1 have not been determined; this reaction is inferred from the one catalyzed by the homologous mouse protein (Zhang et al. 2011).
