The <scene name='Stancu_Phosphoglucoisomerase_Sandbox_1/ | '''Active Site''' - Mammalian PGI shows a degree of <scene name='Stancu_Phosphoglucoisomerase_Sandbox_1/Conservation2/1'>conservation</scene> ( dark red for highly conserved regions - dark blue for variable reigions) of about 90 %. The <scene name='Stancu_Phosphoglucoisomerase_Sandbox_1/Active_site2/1'>active site</scene> is the region with highest observed conservation, with a number of residues that are crucial in the mechanism of the enzyme (Lys210, Gln353, Glu357, Gln511, Lys518, His388b). | ||
Another characteristic of phosphoglucose isomerase is that binding of substrate at the active site, induces a small movement in the conformation of the enzyme. This can be seen in '''Figure 2''' as change in the position of an α helix. | Another characteristic of phosphoglucose isomerase is that binding of substrate at the active site, induces a small movement in the conformation of the enzyme.
