Note

Deoxycytidine monophosphate (dCMP), also known as deoxycytidylic acid or deoxycytidylate in its conjugate acid and conjugate base forms, respectively, is a deoxynucleotide, and one of the four monomers that make up DNA. In a DNA double helix, it will base pair with deoxyguanosine monophosphate. dCMP belongs to the class of organic compounds known as pyrimidine 2'-deoxyribonucleoside monophosphates. These are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. Deficiency of the enzyme deoxycytidine kinase (EC2.7.1.74) is associated with resistance to antiviral and anticancer chemotherapeutic agents, whereas increased enzyme activity is associated with increased activation of these compounds to cytotoxic nucleoside triphosphate derivatives. dCMP exists in all living species, ranging from bacteria to humans. Within humans, dCMP participates in a number of enzymatic reactions. In particular, dCMP can be converted to dCDP by the enzyme UMP-CMP kinase 2. In addition, dCMP can be converted into deoxycytidine, which is catalyzed by the enzyme cytosolic purine 5'-nucleotidase. In humans, dCMP is involved in the metabolic disorder called ump synthase deficiency (orotic aciduria). Outside of the human body, dCMP has been detected, but not quantified in several different foods, such as turnips, garlics, agaves, garden onions, and italian sweet red peppers. dCMP is a deoxycytosine nucleotide containing one phosphate group esterified to the deoxyribose moiety in the 2'-,3'- or 5- positions.
