IntEnz Enzyme Nomenclature


Accepted name:
13-hydroxylupanine O-tigloyltransferase
Other names:
13-hydroxylupanine acyltransferase
tigloyl-CoA:13-hydroxylupanine O-tigloyltransferase
Systematic name:
(E)-2-methylcrotonoyl-CoA:13-hydroxylupanine O-2-methylcrotonoyltransferase



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.
