ABSTRACT
Mutant strains of Saccharomyces cerevisiae unable to utilize allantoin as sole nitrogen murce were isolated and divided into three groups on the basis of their biochemical and genetic characteristics. The three loci associated with these mutant classes were designated dall (allantoinase minus), da12 (allantoicase minus) and da14 (allantoin transport minus). All three loci are located in a cluster that is proximal to the lysl locus on the right arm of chromosome IX. The gene order and intergenic distances were estimated to be: dall—2.5 cM—dal4—1.9cM—dal2—4.6cM—lysl.
