title: Arsenate-resistant alkaline phosphatase-constitutive mutants of Escherichia coli.
abstract: When arsenate-resistant mutants are selected approximately 50 per cent of them are also consitutive for the synthesis of alkaline phosphatase and the Pi-binding protein. Some of these mutants are linked to ilv (phoS- or phoT-), other are linked to proC (phoR-). One of the mutant strains linked to ilv lost the Pi-binding protein (the phoS gene product). Resistance to arsenate, constitutivty for alkaline phosphatase synthesis and loss of the Pi-binding protein occurred pleiotropically by the same phoS- mutation.
