title: Isolation and properties of a thymidylate-less mutant in Saccharomyces cerevisiae.
abstract: A mutant, tmp3, has been isolated in Saccharomyces cerevisiae. Genetic and physiological analysis show that a single mendelian gene controls the multiple requirements for thymidylate, methionine, adenine and histidine and a neutral cytoplasmic petite character. Crude extracts of this mutant present a 60% decrease of serine transhydroxymethylase specific activity as compared to a wild-type strain.
