| EC Number | 3.1.1.112 |
| Enzyme Function | FUNCTION: Plays a crucial role in the hydrolysis of isoamyl acetate in sake mash (Ref.2). Hydrolyzes short chain esters from acetate (C2) to hexanoate (C6), showing more specificity for shorter chain exters. No activity for decanoate (C10) esters (PubMed:21069734). {ECO:0000269|PubMed:21069734, ECO:0000269|Ref.2}. |
