The citrate synthases of the gram-negative bacteria, Escherichia coli and Acinetobacter anitratum, are allosterically inhibited by NADH. The kinetic properties, however, suggest that the equilibrium between active (R) and inactive (T) conformational states is shifted toward the T state in the E. coli enzyme. We have now manipulated the cloned genes for the(More)
The structural gene for the allosteric citrate synthase of Pseudomonas aeruginosa has been cloned from a genomic library by using the Escherichia coli citrate synthase gene as a hybridization probe under conditions of reduced stringency. Subcloning of portions of the original 10-kilobase-pair (kbp) clone led to isolation of the structural gene, with its(More)
