15066989-5	2004	In contrast, in the NO-bound ferric complexes, the addition of l-Arg alone does not affect the structural properties of the Fe-N-O moiety, but H4B binding forces it to adopt a bent structure, which is further enhanced by the subsequent addition of l-Arg.

16445290-3	2006	We analyzed the structural effects of l-arginine (Arg) and tetrahydrobiopterin (H(4)B) binding on several key complexes (ferric, ferrous, ferrous-CO, and ferric-NO) and characterized the bonding properties of the proximal cysteine ligand.
