Effects of mutations at tyrosine 66 and asparagine 123 in the active site pocket of Escherichia coli uracil DNA glycosylase on uracil excision from synthetic DNA oligomers: evidence for the occurrence of long-range interactions between the enzyme and substrate
Uracil DNA glycosylase (UDG), a highly conserved DNA repair enzyme, excises uracil from DNA. Crystal structures of several UDGs have identified residues important for their exquisite specificity in detection and removal of uracil. Of these, Y66 and N123 in Escherichia coli UDG have been proposed to...
