R 1.-.-.- : Hydrolysis (bond cleavage by water) (Reaction)

L 1.13.-.- : Amide bond (One of Carbonyl Ester bonds; including peptide bond) (Ligand group involved)

C 1.13.30000.- : Trypsin-like mechanism (Nucleophile/Acid-Base/Modulator/Stabilizer); Modulator-assisted base activation of nucleophile; Nucleophilic attack on target bond; SN2-like reaction; covalent bond between enzyme and substrate; followed by protonation to leaving group; hydrolysis by base-activated water (Catalytic mechanism)
