EC Number | 3.4.18.1 |
Enzyme Function | FUNCTION: Exhibits carboxy-monopeptidase as well as carboxy-dipeptidase activity (By similarity). Plays an essential role in molting, a process during larval stages in which a new cuticle is formed and the old cuticle is shed (Probable) (PubMed:15555728). Required for the degradation and shedding of the old cuticle (Probable) (PubMed:15555728). {ECO:0000250|UniProtKB:Q9UBR2, ECO:0000269|PubMed:15555728, ECO:0000305|PubMed:8939969}. |
