abstract：:Replacements of Asp-295 by Asn (D295N) and Glu (D295E) decreased the catalytic center activity of Leuconostoc mesenteroides sucrose phosphorylase to about 0.01% of the wild-type level (k(cat)=200s(-1)). Glucosylation and deglucosylation steps of D295N were affected uniformly, approximately 10(4.3)-fold, and independen...
