Abstract
The ADE1 gene from Candida utilis CA(u)-37, a strain used for commercially producing enzymes, was cloned by complementation of the adel mutation of Saccharomyces cerevisiae. It was composed of 903bp, 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.
