3.5.4.1 | 37 | - |
the hyaluronan binding domain of tumor necrosis factor alpha-stimulated gene-6-cytosine deaminase fusion protein retains 20% of its initial enzyme activity after 24 h, 12% after 48 h, and 6% after 124 h at 37°C. In contrast, the activity of cytosine deaminase decreases rapidly at 37°C, and retains only about 5% of initial activity after 24 h | Saccharomyces cerevisiae |
3.5.4.1 | 42 | - |
the melting temperature of cytosine deaminase is at 42°C | Saccharomyces cerevisiae |
