Abstract excerpt
We describe a mutant of Escherichia coli citrate synthase, CS R319L, in which the arginine residue at position 319 of the sequence has been replaced by leucine. In this mutant, saturation by the substrate acetyl-CoA is changed from sigmoid (Hill parameter = 1.75 +/- 0.2) to hyperbolic (Hill parameter = 1.0 +/- 0.1) and dependence on the activator KCl is greatly reduced. Further mutations at this site and at...
