Abstract: | The 6636 bp of the yeast URA2 gene encoding the carbamoylphosphate synthetase-aspartate transcarbamylase complex have been sequenced. The protein is organized into four regions, three of which are functional domains as indicated previously by genetic analysis. The fourth domain corresponds to a defective dihydroorotase called DHOase-like. The URA2 gene complex with the same organization as the equivalent genes in higher eukaryotes suggests an evolution from a common ancestral gene. |
