title: Role of Escherichia coli beta-ketoacyl-ACP synthase I in unsaturated fatty acid synthesis.
abstract: Two activities were found in E. coli extracts which could complement unsaturated fatty acid synthesis of a cerulenin treated E. coli fatty acid synthetase. One of these is beta-ketoacyl-ACP synthase I, but it is not known whether the other activity represents the previously characterized beta-ketoacyl-ACP synthase II. A mutant strain exhibiting a temperature sensitive unsaturated fatty acid synthetic activity apparently lacked an active beta-ketoacyl-ACP synthase I.
