Figure 7.

Stereo view of the NAD binding site. Cartoon representation of CpGAPDH (holo, subunit A) in wheat color superimposed on the O subunit of human GAPDH holoenzyme structure (PDBID: 1ZNQ) shown in white. CpGAPDH residues M37 and N185 are shown in stick (color coding C: orrange, N:blue, O: red and S: yellow) along with corresponding human GAPDH residues I38 and T184(C: white, N: blue and O: red). NAD molecule is also shown in stick (C: rose, N: blue and O: red). NAD atoms nearest to M37 and N185 are connected with dotted lines.
