RESUMO
Cell-free extracts of Mycoplasma mycoides subsp. mycoides were assayed for enzymes associated with the salvage synthesis of pyrimidine deoxyribonucleotides. They possessed kinases for deoxycytidine, (d)CMP, thymidine (deoxyuridine), dTMP, and nucleoside diphosphates; dCTPase and dUTPase; dCMP deaminase; thymidine (deoxyuridine) phosphorylase; and dUMP (dTMP) phosphatase. The existence of these enzymic activities together with ribonucleoside diphosphate reductase explains the capacity of cytidine to provide M. mycoides with deoxyribose for the synthesis of thymidine nucleotides from thymine.
