Catalyzes the hydrolytic deamination of cytosine to uracil. Is involved in the pyrimidine salvage pathway, which allows the cell to utilize cytosine for pyrimidine nucleotide synthesis. Is also able to catalyze deamination of isoguanine, a mutagenic oxidation product of adenine in DNA, and of isocytosine. To a lesser extent, also catalyzes the conversion of 5-fluorocytosine (5FC) to 5-fluorouracil (5FU); this activity allows the formation of a cytotoxic chemotherapeutic agent from a non-cytotoxic precursor.

Fe2+-CDase is rapidly inactivated by H2O2, whereas Mn2+-CDase, Co2+-CDase, and Zn2+-CDase are not inactivated by H2O2. CDase is also inhibited by excess divalent cations (PubMed:8226944). Phosphonocytosine, a mimic of the tetrahedral reaction intermediate, inhibits the deamination of cytosine with a Ki of 52 nM (PubMed:21545144).2 Publications

<p>The checksum is a form of redundancy check that is calculated
from the sequence. It is useful for tracking sequence updates.</p>
<p>It should be noted that while, in theory, two different sequences could
have the same checksum value, the likelihood that this would happen
is extremely low.</p>
<p>However UniProtKB may contain entries with identical sequences in case
of multiple genes (paralogs).</p>
<p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64)
using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
The algorithm is described in the ISO 3309 standard.
