Design of an adenosine phosphorylase by active-site modification of murine purine nucleoside phosphorylase. Enzyme kinetics and molecular dynamics simulation of Asn-243 and Lys-244 substitutions of purine nucleoside phosphorylase.

Our objective was to alter the substrate specificity of purine nucleoside phosphorylase such that it would catalyse the phosphorolysis of 6-aminopurine nucleosides. We modified both Asn-243 and Lys-244 in order to promote the acceptance of the C6-amino group of adenosine. The Asn-243-Asp substitutio...
