Protein

Phosphatidic acid phosphohydrolase 1

Gene

PAH1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Mg2+-dependent phosphatidate (PA) phosphatase which catalyzes the dephosphorylation of PA to yield diacylglycerol. Required for de novo lipid synthesis and formation of lipid droplets. Controles transcription of phospholipid biosynthetic genes and nuclear structure by regulating the amount of membrane present at the nuclear envelope. Involved in plasmid maintenance, in respiration and in cell proliferation.9 Publications

Catalytic activityi

A 1,2-diacylglycerol 3-phosphate + H2O = a 1,2-diacyl-sn-glycerol + phosphate.3 Publications

Cofactori

Mg2+1 Publication

Enzyme regulationi

Phenylglyoxal and propranolol inhibit activity in dose-dependent manners with IC50 values of 1.3 mM and 0.2 mM, respectively.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
