Cloning and characterization of the adenine phosphoribosyltransferase-encoding gene (APT1) from Saccharomyces cerevisiae.

We have cloned, sequenced and characterized the APT1 (adenine phosphoribosyltransferase) gene from Saccharomyces cerevisiae. The APT1 sequence includes an open reading frame encoding 221 amino acids and is contained within a 1322-bp insert that complements APRT-deficient mutants to wild-type levels of enzyme activity. Analysis by primer extension revealed multiple transcription start points (tsp) and a major tsp 21-bp upstream from the ATG start codon. A transcript initiated at the major tsp would yield a 700-nt mRNA which is in agreement with the size observed by Northern analysis. Sequence comparison indicates that the yeast enzyme shares strong similarities with other known APRT of bacterial, invertebrate, plant and mammalian origins.[1]
