Introduction and General Structure

can be observed. Aldolase is an enzyme that is active during glycolysis, which is an overall series of reactions that produces cellular energy (ATP). Specifically, aldolase catalyzes an aldol cleavage reaction that hydrolyzes fructose 1,6-bisphosphate. It is a tetrameter (four subunits)composed of alpha helices and beta sheets (). Please note that alpha helices are observed in blue, and beta sheets are in yellow. The majority of the helices are located on the surface (outside) of the enzyme, where as most of the sheets are found in the interior. Most likely, polar amino acids are located on the peripheral helices, while hydrophobic or paired-polar amino acids are found within the beta sheet.

Hydrogen and Disulfide Bonds

The > for aldolase allow the protein proper stability. Hydrogen bonds are in red (there are plenty of them), and disfulfide bonds would appear as black. However, please note that there are no observable disulfide bonds in this picture.
