2'-脱氧胞苷5'-单磷酸（dCMP）利用尿苷单磷酸（UMP）/单磷酸胞苷（CMP）激酶（EC 2.7.4.4）的底物，形成dCDP，其在磷酸化为dCTP时支持DNA生物合成。 It consists of a 2′-deoxy-β-D-ribofuranose, linked through an N-β-D-glycosidic linkage to a heterocycle nitrogen cytosine. 2′-Deoxycytidine 5′-monophosphate (dCMP) is used as a substrate of uridine monophosphate (UMP)/cytidine monophosphate (CMP) kinase (EC 2.7.4.4) to form dCDP which upon phosphorylation to dCTP supports DNA biosynthesis. It consists of a 2′-deoxy-β-D-ribofuranose, linked through an N-β-D-glycosidic linkage to a heterocycle nitrogen cytosine.
