Summary
The phoE locus, one of the loci in which mutations lack the activity for repressible acid phosphatase, was found to be the structural gene for the enzyme by examining the enzymic characteristics of repressible acid phosphatase activity using cell extracts prepared from the leaky phoE mutants, the PHOE revertants and the PHOE recombinants between the different phoE mutants. Other evidence which strongly suggests that the phoC locus is coding for the constitutive acid phosphatase was obtained by a similar investigation. Although the phoC and phoE loci are tightly linked, they were separable by meiotic recombination.
