Dipeptides 34-43 nitric oxide synthase 1 Homo sapiens 112-116 16285725-2 2005 Crystal structures of these dipeptides bound to both isoforms revealed two different conformations, curled in nNOS and extended in eNOS, corresponding to higher and lower binding affinity to the two isoforms, respectively. Dipeptides 28-38 nitric oxide synthase 1 Homo sapiens 110-114 16285725-5 2005 Another residue farther away from the active site, Met336 in nNOS (Val106 in eNOS), is in contact with bulkier dipeptide inhibitors. Dipeptides 111-120 nitric oxide synthase 1 Homo sapiens 61-65 16285725-7 2005 Here we report crystal structures and inhibition constants for bulkier dipeptide inhibitors bound to nNOS and eNOS that illustrate the important role played by residues near the entry to the active site in isoform selective inhibition. Dipeptides 71-80 nitric oxide synthase 1 Homo sapiens 101-105
