From: Inhibition of homoserine dehydrogenase by formation of a cysteine-NAD covalent complex

Effects of cysteine and NAD on the backbone atoms. The backbone atoms of the amino acid residues comprising the ligand-bound and native structures are superimposed. The background colors pink, light green, and light blue indicate the nucleotide-binding, dimerization, and catalytic regions, respectively.
