The catalytic reaction mechanism and binding of substrates was investi-gated for the multisubstrateDrosophila melanogasterdeoxyribonucleosidekinase. Mutation of E52 to D, Q and H plus mutations of R105 to K andH were performed to investigate the proposed catalytic reaction mech-anism, in which E52 acts as an initiating base and R105 is thought to sta-bilize the transition state of the reaction.
