Substrate specificity of E. coli thymidine phosphorylase to pyrimidine nucleoside modified at 5 '-, 3 '-, and 2 '-positions of sugar moiety has been studied. Equilibrium (Keq) and kinetics constants of phosphorolysis reaction of nucleosides were measured. The most important hydrogen bonds in enzyme-substrate complex have been determined.
