(E)-2-methylcrotonoyl-CoA:13-hydroxylupanine O-2-methylcrotonoyltransferase

(E)-2-methylcrotonoyl-CoA + 13-hydroxylupanine = CoA + 13-[(E)-2-methylcrotonoyl]oxylupanine [RN:R04205]

R04205

(E)-2-methylcrotonoyl-CoA [CPD:C03345];
13-hydroxylupanine [CPD:C02621]

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.
