PURL: https://purl.expasy.org/enzyme/EC/1.14.14.168

Accepted Name

germacreene A acid 8beta-hydroxylase

Alternative Name(s)

CYP71BL1

CYP71BL6

Reaction catalysed

germacra-1(10),4,11(13)-trien-12-oate + reduced [NADPH--hemoprotein reductase] + O2 = 8beta-hydroxygermacra-1(10),4,11(13)-trien-12-oate + oxidized [NADPH--hemoprotein reductase] + H2O + H(+)

Comment(s)

A cytochrome P450 (heme-thiolate) protein from the plant Helianthus annuus (common sunflower).
The cyclisation of 8beta-hydroxygermacra-1(10),4,11(13)-triene-12- oate to inunolide (12,8beta) does not seem to occur spontaneously.
The enzyme from Inula hupehensis also forms some 8alpha- hydroxygermacra-1(10),4,11(13)-triene-12-oate, which spontaneously cyclises to 8-epi-inunolide (12,8alpha) (cf. EC 1.14.14.170).
