title: Presence of a specific uridine 5'-monophosphate pyrophosphorylase in baker's yeast.
abstract: Uridine 5'-monophosphate pyrophosphorylase was found to be present in baker's yeast. The enzyme preparation, purified about 30-fold, shows a strict specificity toward uracil and requires Mg++ for its activity.
