| EC Number | 3.1.1.1 |
| Enzyme Function | FUNCTION: Esterase likely involved in ester/lipid metabolism. Shows strong substrate selectivity toward short, straight chain alkyl esters with the highest activity toward four atom chains. The physiological substrate is unknown (PubMed:25354081). Is able to hydrolyze ester bonds within a wide range of p-nitrophenyl derivatives (C2-C14) in vitro (PubMed:20957207). {ECO:0000269|PubMed:20957207, ECO:0000269|PubMed:25354081}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is 39 degrees Celsius for the hydrolysis of p-nitrophenyl hexanoate. {ECO:0000269|PubMed:20957207}; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 8.0 for the hydrolysis of p-nitrophenyl hexanoate. {ECO:0000269|PubMed:20957207}; |
