  • Thermally stable cytosine deaminase from saccharomyces
    Patent number: 5545548
    Abstract: Thermally stable cytosine deaminase (CDase), and the gene coding therefor, is disclosed as well as methods of isolating, purifying, and recombinantly producing the same. The thermally stable CDase can be isolated from Saccharomyces cerevisiae. The yeast isolated enzyme has a molecular weight of approximately 32 kDa, as determined by gel filtration chromatography, and is composed of two subunits, each with a molecular weight of about 17 kDa. Thermally stable yeast CDase so purified shows no significant sequence homology with other known sequenced proteins.
