| Enzyme Function | FUNCTION: Coenzyme A-dependent lysophosphatidic acid acyltransferase that catalyzes the transfert of an acyl group on a lysophosphatidic acid (PubMed:19801371). Functions preferentially with 1-oleoyl-lysophosphatidic acid followed by 1-palmitoyl-lysophosphatidic acid, 1-stearoyl-lysophosphatidic acid and 1-arachidonoyl-lysophosphatidic acid as lipid acceptor (PubMed:19801371). Functions preferentially with arachidonoyl-CoA followed by oleoyl-CoA as acyl group donors (PubMed:19801371). Functions in phosphatidic acid biosynthesis (By similarity). May regulate the cellular storage of triacylglycerol through activation of the phospholipase PNPLA2 (PubMed:16679289). Involved in keratinocyte differentiation (By similarity). Regulates lipid droplet fusion (PubMed:26083785). {ECO:0000250|UniProtKB:Q8WTS1, ECO:0000269|PubMed:16679289, ECO:0000269|PubMed:19801371, ECO:0000269|PubMed:26083785}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Preincubation of the enzyme for 10 min at temperatures above 35 degrees Celsius decreases acyltransferase activity subsequently measured at 30 degrees Celsius. Acyltransferase activity is reduced by approximately 60% following 10 min preincubation at47 degrees Celsius. {ECO:0000269|PubMed:19801371}; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 7-8.5. {ECO:0000269|PubMed:19801371}; |
