Reaction: (E)-2-methylcrotonoyl-CoA + 13-hydroxylupanine = CoA + 13-[(E)-2-methylcrotonoyl]oxylupanine
Glossary: (E)-2-methylcrotonoyl-CoA = tigloyl-CoA = (E)-2-methylbut-2-enoyl-CoA
Other name(s): tigloyl-CoA:13-hydroxylupanine O-tigloyltransferase; 13-hydroxylupanine acyltransferase
Systematic name: (E)-2-methylcrotonoyl-CoA:13-hydroxylupanine O-2-methylcrotonoyltransferase
Comments: 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.
