title: Mapping of the proteinase b structural gene PRB1, in Saccharomyces cerevisiae and identification of nonsense alleles within the locus.
abstract: We report the mapping of the structural gene for proteinase B, PRB1. It is located 1.1 cM proximal to CAN1 on the left arm of chromosome V of Saccharomyces cerevisiae. We have identified 34 amber and 12 ochre mutations among the 126 prb1 mutations in our collection.
