What's a GeneRIF?

Cytosine deaminase residue glutamate64 plays a critical role in the activation of anticancer prodrug 5-fluorocytosine, indicating importance not only for the deamination reaction but also for binding of the substrate.
Title: Role of glutamate 64 in the activation of the prodrug 5-fluorocytosine by yeast cytosine deaminase.

Preferred Names: cytosine deaminase

NP_015387.1

EC 3.5.4.1

Cytosine deaminase; zinc metalloenzyme that catalyzes the hydrolytic deamination of cytosine to uracil; of biomedical interest because it also catalyzes the deamination of 5-fluorocytosine (5FC) to form anticancer drug 5-fluorouracil (5FU)
