• Enzyme: Fructose biphosphate aldolase
• Substrate: fructose-1,6-biphosphate
• Products: glyceraldehyde-3-phosphate and dihydroxiacetone-phosphate.

This shows secondary structures in Fructose biphosphate aldolase molecule.

This shows the polypeptide chain skeleton and amino acids R groups.

The polypeptide chain of this enzyme consist of .

Now, we are going to to highligth the enzyme

Active site is surrounded by

, i.e., fructose-1,6-biphosphate. fits into active site.

In this , fit between active site and substrate is best seen.
