-
enzyme is responsible for the conversion of beta-carotene via beta-isorenieratene to isorenieratene by a desaturation/methyltransferation mechanism. Upon introduction of two additional double bonds leading to amortization of the ionone ring, one of the methyl groups of C-1 (and also 1' at the other side) is lost and transferred to position 2
