| EC Number | 3.1.1.32 |
| Enzyme Function | FUNCTION: Catalyzes the hydrolysis of phosphatidylcholine with phospholipase A1 (EC 3.1.1.32) activity (PubMed:23159790). Shows hemolytic activity (By similarity). Shows a phospholipase A1 enzymatic activity of 3.6 U/ml (PubMed:23159790). In vivo, a mixture of this protein and Ves a 1.02 is able to paralyze crickets (PubMed:23159790). {ECO:0000250|UniProtKB:P0DMB7, ECO:0000269|PubMed:23159790}. |
