| EC Number | 3.1.1.-; 3.5.2.6 |
| Enzyme Function | FUNCTION: Shows both esterase and beta-lactamase activities, with a much higher activity against phenyl esters than against beta-lactams (PubMed:26398213, PubMed:26672466). Shows esterase activity against both long-chain and short-chain p-nitrophenol (pNP) esters, with a preference for shorter chain esters (PubMed:26398213, PubMed:26672466). Hydrolyzes substrates containing beta-lactam ring such as nitrocefin and ampicillin (PubMed:26672466). Functions as an immunogen that activates both humoral and cell-mediated responses (PubMed:26398213). {ECO:0000269|PubMed:26398213, ECO:0000269|PubMed:26672466}. |
