title: Acyl-CoA: 6-APA acyltransferase from Penicillium chrysogenum studies on its hydrolytic activity.
abstract: Acyl-CoA: 6-APA acyltransferase (AT) from Penicillium chrysogenum Wis 54-1255 catalyzes the hydrolysis of different acyl-CoA derivatives generating, in the absence of 6-APA, free acid and CoA. The hydrolytic efficiency of AT is highest for acyl-CoA variants in which the acyl-moiety is higher than six carbon atoms. The maximal rate of catalysis was achieved in 50 mM Tris-HCl buffer, pH 8.5 at 35 degrees C. Unlike the AT activity, the acylase activity has a different optimum temperature and substrate specificity and dithiothreitol is not required for the reaction.
