Gensor Unit       
Name: CytR
Description: CytR negatively regulates the expression of genes involved in nucleoside and nucleotide transport and catabolic processes, in the absence of cytidine. The presence of cytidine induces the expression of genes related to the transport of nucleosides and nucleotides (e.g., uridine, inosine, 2′-deoxyuridine, etc.) and their transformation to ribose, ammonia, acetaldehyde, and glyceraldehyde-3-P.
