Yeast mutants deficient in orotidine-5'-phosphate (OMP) pyrophosphorylase activity have been obtained. The gene encoding this enzyme is unlinked to the four pyrimidine genes previously described. The ...
From a genomic library of the filamentous fungus Podospora anserina, we have cloned a 4.9-kb fragment which complements an Escherichia coli mutant strain deficient for orotidylic acid pyrophosphorylas...
