EC 1.14.13.147      
Transferred entry: taxoid 7β-hydroxylase. Now EC 1.14.14.182, taxoid 7β-hydroxylase
[EC 1.14.13.147 created 2012, deleted 2022]
 
 
EC 1.14.14.182     
Accepted name: taxoid 7β-hydroxylase
Reaction: (1) taxusin + [reduced NADPH—hemoprotein reductase] + O2 = 7β-hydroxytaxusin + [oxidized NADPH—hemoprotein reductase] + H2O
(2) 2α-hydroxytaxusin + [reduced NADPH—hemoprotein reductase] + O2 = 2α,7β-dihydroxytaxusin + [oxidized NADPH—hemoprotein reductase] + H2O
Glossary: taxusin = taxa-4(20),11-diene-5α,9α,10β,13α-tetrayl tetraacetate
Systematic name: taxusin, [reduced NADPH—hemoprotein reductase]:oxygen 7-oxidoreductase
Comments: A cytochrome P-450 (heme-thiolate) protein from the yew tree Taxus cuspidata. Does not act on earlier intermediates in taxol biosynthesis.
