Crystal structure of the double mutant (D52N/R367Q) of NT5C2-537X in the active state, Northeast Structural Genomics Target


Function and Biology Details

Reactions catalysed:
A nucleotide + a 2'-deoxynriboucleoside = a nucleoside + a 2'-deoxyribonucleoside 5'-phosphate
A 5'-ribonucleotide + H(2)O = a ribonucleoside + phosphate
IMP + H(2)O = inosine + phosphate
