IUBMB Comments
Unlike EC, uridine phosphorylase, and EC, thymidine phosphorylase, this enzyme can accept both the ribonucleoside uridine and the 2'-deoxyribonucleosides 2'-deoxyuridine and thymidine . The reaction is reversible, and the enzyme does not distinguish between alpha-D-ribose 1-phosphate and 2-deoxy-alpha-D-ribose 1-phosphate in the synthetic direction.

molecular basis of catalytic chamber-assisted unfolding and cleavage of human insulin by human insulin-degrading enzyme, IDE utilizes the interaction of its exosite with the N-terminus of the insulin A chain, overview. The unique size, shape, charge distribution, and exosite of the IDE catalytic chamber contribute to its high affinity for insulin
