EC 3.1.3.81 Details
EC number
3.1.3.81
Accepted name
diacylglycerol diphosphate phosphatase
Reaction
1,2-diacyl-sn-glycerol 3-diphosphate + H2O = 1,2-diacyl-sn-glycerol 3-phosphate + phosphate
Other name(s)
DGPP phosphatase, DGPP phosphohydrolase, DPP1, DPPL1, DPPL2, PAP2, pyrophosphate phosphatase
Systematic name
1,2-diacyl-sn-glycerol 3-phosphate phosphohydrolase
Comment
The bifunctional enzyme catalyses the dephosphorylation of diacylglycerol diphosphate to phosphatidate and the subsequent dephosphorylation of phosphatidate to diacylglycerol (cf. phosphatidate phosphatase (EC 3.1.3.4)). It regulates intracellular levels of diacylglycerol diphosphate and phosphatidate, phospholipid molecules believed to play a signalling role in stress response [6]. The phosphatase activity of the bifunctional enzyme is Mg2+-independent and N-ethylmaleimide-insensitive and is distinct from the Mg2+-dependent and N-ethylmaleimide-sensitive enzyme EC 3.1.3.4 (phosphatidate phosphatase) [5].The diacylglycerol pyrophosphate phosphatase activity in Saccharomyces cerevisiae is induced by zinc depletion, by inositol supplementation, and when cells enter the stationary phase [4].
