hydrolases

Enzymes (EC class 3) cleaving substrates with addition of H2O at the point of cleavage; e.g., esterases, phosphatases, nucleases, peptidases. SYN: hydrolyzing enzymes.
- cysteine h. h. that utilize an active site cysteinyl residue for the catalytic event.
- serine h. h. that utilize an active site seryl residue for the catalytic event.
