ENZYME: 4.2.3.96

Entry

EC 4.2.3.96                 Enzyme

Name

avermitilol synthase

Class

Lyases;
Carbon-oxygen lyases;
Acting on phosphates

Sysname

avermitilol hydrolase (cyclizing, avermitilol-forming)

Reaction(IUBMB)

(2E,6E)-farnesyl diphosphate + H2O = avermitilol + diphosphate [RN:R09896]

Reaction(KEGG)

R09896

Substrate

(2E,6E)-farnesyl diphosphate [CPD:C00448];
H2O [CPD:C00001]

Product

avermitilol [CPD:C20181];
diphosphate [CPD:C00013]

Comment

Requires Mg2+. The recombinent enzyme gives avermitilol (85%) plus traces of germacrene A, germacrene B and viridiflorol. The (1S)-hydrogen of farnesyl diphosphate is retained.
