Primary structure of the ADE1 gene from Candida utilis

The ADE1 gene from Candida utilis CA(u)-37, a strain used for commercially producing enzymes, was cloned by complementation of the ade1 mutation of Saccharomyces cerevisiae. It was composed of 903 bp, and the deduced amino acid sequence was 70% homologous to those of the ADE1 genes of S. cerevisiae and Candida maltosa. The highly preserved region of SAICAR synthetase, the ADE1 gene product, was also found by a homology search.
