A Dominant Constitutive phoR Mutation in ESCHERICHIA COLI

AUTOR(ES)
RESUMO

A dominant constitutive mutation of the phoR locus controlling alkaline phosphatase synthesis in Escherichia coli is described. Its phenotype can be explained by the production of a poisonous subunit of the phoR gene product. The phoR gene product is inferred to consist of at least 3 or 4 subunits.
