The third conserved c ysteine, C72 in the M. tuberculosisenzyme, corresponding to C176 in the E. coli enzyme, islocated near the S-AdoMet binding site but far from theactive site. T herefore, it was reasonable to postulate animportant[r]

Tovalidate the docking protocol, it was first applied to threedifferent experimental protein–heparin complexes depositedat the Protein Data Bank (PDB) files [31], PDB code 1bfc,1azx, 1e0o [32–34].
