4.2.1.55	metabolism	the enzyme is involved in benzoyl-coenzyme A degradation	-, 729651	
4.2.1.55	additional information	substrate binding pocket structure and mechanism, overview. CaCRT uses a unique CoA binding mode. The Ser69 residue in CaCRT is hydrogen-bonded with N6 of AcAc-CoA, in contrast to the corresponding Lys101 and Val74 residues in ECH and DmdD, and is involved in the stabilization of the adenine ring. Moreover, Ala24 of CaCRT is located near the phosphate moiety, whereas the corresponding Lys31 residue of DmdD is hydrogen-bonded with this moiety	746965	
4.2.1.55	physiological function	the enzyme catalyzes the dehydration of 3-hydroxybutyryl-CoA to crotonyl-CoA in the n-butanol biosynthetic pathway, molecular mechanism	746965
