Reaction(IUBMB)
(E)-2-methylcrotonoyl-CoA + 13-hydroxylupanine = CoA + 13-[(E)-2-methylcrotonoyl]oxylupanine [RN:R04205]
Reaction(KEGG)
Substrate
(E)-2-methylcrotonoyl-CoA [CPD:C03345];
13-hydroxylupanine [CPD:C02621]
Product
CoA [CPD:C00010];
13-[(E)-2-methylcrotonoyl]oxylupanine
Comment
Benzoyl-CoA and, more slowly, pentanoyl-CoA, 3-methylbutanoyl-CoA and butanoyl-CoA can act as acyl donors. Involved in the synthesis of lupanine alkaloids.
