Fatty Acid Activation by a Lipophilic Bacterium
Overview
Affiliations
Cell-free extracts of Nocardia asteroides activated saturated fatty acids from octanoate to octadecanoate, plus docosanoate; maximal activation occurred with dodecanoate. No activation of short-chain fatty acids was observed. The activating enzyme, characterized as an acyl-coenzyme A (Co A) synthetase (acid: Co A ligase [adenosine monophosphate]; EC 6.2.1.3), was localized in the cytoplasm of the cells and had absolute requirements for Co A, adenosine 5'-triphosphate, and Mg(2+). Kinetic data suggested that N. asteroides possessed at least two synthetases: one specific for short-chain fatty acids, and the other specific for medium- and long-chain fatty acids.
