Ligand screening of selected purine-type nucleobase derivatives against the MA0940 gene product. Compounds screened are (a) guanosine, (b) adenosine, (c) 5,6-dimethylbenzimidazole, and (d) 6-chloropurine riboside. The peaks labeled NH2 in (a) and (b) are exchangeable purine amino groups that are manifested as positively phased peaks in the waterLOGSY experiment.
