In enzymology, a nucleoside deoxyribosyltransferase (EC 2.4.2.6) is an enzyme that catalyzes the chemical reaction
2-deoxy-D-ribosyl-base1 + base2Thus, the two substrates of this enzyme are 2-deoxy-D-ribosyl-base1 and base2, whereas its two products are 2-deoxy-D-ribosyl-base2 and base1.
This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is nucleoside:purine(pyrimidine) deoxy-D-ribosyltransferase. Other names in common use include purine(pyrimidine) nucleoside:purine(pyrimidine) deoxyribosyl, transferase, deoxyribose transferase, nucleoside trans-N-deoxyribosylase, trans-deoxyribosylase, trans-N-deoxyribosylase, trans-N-glycosidase, nucleoside deoxyribosyltransferase I (purine nucleoside:purine, deoxyribosyltransferase: strictly specific for transfer between, purine bases), nucleoside deoxyribosyltransferase II [purine(pyrimidine), and nucleoside:purine(pyrimidine) deoxyribosyltransferase]. This enzyme participates in pyrimidine metabolism.
