    摘要: The invention provides a method of determining the deaminase activity of the enzymes transforming cytosine derivatives into uracil derivatives in a sample, wherein the sample is incubated with a substrate of an enzyme selected from a group comprising 5-ethynyl-2'- deoxycytidine (EdC), 5-bromo-2'-deoxycytidine (BrdC), 5-chloro-2'-deoxycytidine (CldC), 5-iodo-2'-deoxycytidine (IdC), 5-ethynylcytidine (EC), 5-bromocytidine (BrC), 5- chlorocytidine (CIC), 5-iodocytidine (IC) and 5-fluorocytidine (FC), whereas the substrates in the presence of enzymes transforming cytosine derivatives into uracil derivatives are subsequently transformed in the sample into deaminated products, EdC is transformed into 5-ethynyl-2'-deoxyuridine (EdU), BrdC into 5-bromo-2'-deoxyuridine (BrdU), CldC into 5-chloro-2'-deoxyuridine (CldU), IdC into 5-iodo-2'-deoxyuridine (IdU), EC into 5- ethynyluridine (EU), BrC into 5-bromouridine (BrU), CIC into 5-chlorouridine (CIU), IC into 5-iodouridine (IU) and FC into 5-fluorouridine (FU), these deaminated products are subsequently detected in the DNA or RNA and the amount of incorporated EdU, BrdU, CldU, or IdU in the DNA, and EU, BrU, CIU, IU, or FU in the RNA are determined. The invention also includes the use of the above-mentioned method for determining the deaminase activity in cells treated with substances, which influence the deaminase activity of the enzymes transforming cytosine derivatives into uracil derivatives.
