Abstract/OtherAbstract:
Three phenylacyl-CoA ligase activities were detected in extracts of Pseudomonas putida CA-3 cells grown with a variety of aromatic carboxylic acids. The three phenylacyl-CoA enzyme activities measured were phenylpropyl-CoA ligase (acting on both phenylpropanoic acid and cinnamic acid), a phenylacetyl-CoA ligase, and a medium chain length phenylalkanoyl-CoA ligase acting on aromatic substrates with 5 or more carbons in the acyl moiety. The rate of each enzyme activity detected in extracts of P. putida CA-3 cells is dependent on the growth substrate supplied. High rates of phenylpropyl-CoA ligase activity were observed with extracts of cells grown on phenylpropanoic acid, cinnamic acid or medium chain length phenylalkanoic acids with an uneven number of carbons in the acyl moiety. Extracts of P. putida CA-3 cells exhibited high rates of phenylacetyl-CoA ligase activity when grown on phenylacetic acid or medium chain length phenylalkanoic acids with an even number of carbons in the acyl moiety. In addition, high rates of medium chain length phenylalkanoyl-CoA ligase activity, towards phenylvaleric acid and phenylhexanoic acid, were exhibited by extracts of cells grown on all medium chain length phenylalkanoic acids. Low levels of the various phenylacyl-CoA ligase activities were found in extracts of cells grown on benzoic acid and glucose. Benzoyl-CoA ligase activity was not detected in any cell free extracts generated in this study.
