Figure 3
A structural comparison of phosphoglucose isomerase from Bacillus (left) and rabbit (right). The structure obtained from B. stearothermophilus (PDB code 2pgi ) was superimposed onto the monomer A of the native rabbit structure and both folds are plotted in ribbon format. Each is colored blue to red, corresponding to the N-terminal to C-terminal direction. Note the additional series of α-helices at the N-terminus of the rabbit enzyme (colored in blue), which are all absent in the Bacillus enzyme. Note also the different locations of the `hook' which, in this view, is located at the top right of the rabbit structure but is found at the top left of the Bacillus enzyme. This figure was prepared using MOLSCRIPT (Kraulis, 1991BB58).
