Figure 9
Superposition of the non-ligand-bound form and the PEP-bound form of Sa_enolase shown as a stereoview. The catalytic loop L1 in the non-ligand-bound form is coloured blue. The `open' and `closed' forms of the catalytic loop L1 in the PEP-bound structure are coloured red and green, respectively. The catalytic loops L2 and L3 are coloured cyan and yellow, respectively. PEP is shown as sticks. Mg2+ ions are coloured blue for the non-ligand-bound structure and purple for the PEP-bound structure. The rest of the structure is coloured grey. The distance corresponding to the conformational change of catalytic loop 1 is labelled in black. |
