additional information butyryl-CoA is about 10% as effective as acetyl-CoA, enzyme catalyzes the transfer of acetyl from acetyl-CoA to thiogalactosides but not or at much slower rate to galactosides except when a phenyl group is attached to the oxygen atom at carbon 1, a phenyl group substitution also allows glucosides to react Escherichia coli ?
