EC 3.1.1.51

Accepted name: phorbol-diester hydrolase

Reaction: phorbol 12,13-dibutanoate + H2O = phorbol 13-butanoate + butanoate

Other name(s): diacylphorbate 12-hydrolase; diacylphorbate 12-hydrolase; phorbol-12,13-diester 12-ester hydrolase; PDEH

Systematic name: 12,13-diacylphorbate 12-acylhydrolase

Comments: Hydrolyses the 12-ester bond in a variety of 12,13-diacylphorbols (phorbol is a diterpenoid); this reaction inactivates the tumour promotor 12-O-tetradecanoylphorbol-13-acetate from croton oil.
