title: Kinetic properties of Mg, Ca ATPase from various Escherichia coli mutants.
abstract: The ATPase is not lacking in the ATPase mutants DL 54 and AN 120 but has very different kinetic properties including a higher Cl- optimum and higher Km values for MgATP. In AN 120, the ATPase activity also has a higher Mg2+ optimum.
