RESUMO
Five additional mutants of Neurospora crassa have been isolated that lack the repressible alkaline phosphatase. The mutations in these strains map at a previously assigned locus on Linkage Group V designated pho-2 (Gleason and Metzenberg 1974). The five new mutants, as well as three previously isolated by Gleason and Metzenberg (1974), were examined for the presence of cross-reacting material to antibody prepared against purified wild-type enzyme. Two of the mutants produced high levels of cross-reacting material, thus providing evidence that the pho-2 locus includes the structural gene for the repressible alkaline phosphatase. Two revertants were obtained from one of the mutants that contained cross-reacting material. Neither revertant produced an enzyme that could be distinguished physicochemically from that of wild type. A method for measuring very low levels of repressible alkaline phosphatase in crude extracts is also described.
