These findings can be explained by the coor- dination of l-arginine in the active ... substrate. For example, in AsnO, a trans con- former is selected for the v 1 torsion angle of bound l-asparagine, whereas in VioC, a gauche(–) rotamer is observed for...

Interestingly, a similar metal ion binding mode to the tandem guanines has been observed in the ... spectrum. Therefore, in order to gain a glo- bal insight into metal ion–RNA interactions, it is often necessary to conduct structural studies of metal ion binding modes in RNA molec...
