Enzyme Function | FUNCTION: Carboxylesterase present at high level in urine that regulates production of felinine, a probable pheromone precursor. Probably acts by hydrolyzing the peptide bond of the felinine precursor 3-methylbutanol cyteinylglycine, producing felinine and glycine in cat urine. {ECO:0000269|PubMed:17052611}. |
