L 1.14.-.- : Thioester (One of Carbonyl Ester bonds) (Ligand group involved)

Catalytic mechanisms

1.14.200.- : Pepsin-like mechanism (Acid-Base/Stabilizer); Water activation by base; SN2-like nucleophilic attack by activated water; Stabilization of transition-state; Protonation to leaving group by acid

1.14.800.- : GDP mannose dehydrogenase final step-like mechanism (Base/Stabilizer); Base-activated water directly attacks on substrate; Stabilization of transition-state; Collapse of transition-state leads to release of leaving group

1.14.10105.- : Glyoxalase-II-like mechanism (Modulator); Inorganic cofactor-assisted water activation; Inorganic cofactor-assisted stabilization of transition-state; Inorganic-cofactor interaction with water/intermediate (atom adjacent to scissile bond)

1.14.30000.- : 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

1.14.36110.- : 4-hydroxybenzoyl-CoA thioesterase-like mechanism (Nucleophile/Acid-Base/Stabilizer); SN1-like reaction induced by stabilizer; covalent bond formation between nucleophile and target atom; Acid protonation to leaving group; intermediate stablilized; covalent bond attacked by base-activated water; intermediate stabilized
