Structure of NM-IIAntr. (a) Stereo figure of a Cα-trace of NM-IIANtr with every twentieth residue numbered (b) Stereo figure of a ribbon diagram of NM-IIANtr with secondary structure elements labelled (α-helices 1–4; β-strands 1–5). The active site residue H67 is displayed as ball-and-stick. (c) Stereo figure of an overlay of NM-IIANtr (green) and E. coli IIANtr (red) (d) Stereo figure of an overlay of NM-IIANtr(green) and E. coli IIAmtl(red).
