[5] This enzyme catalyzes the first step of the Leloir pathway, which is involved in galactose metabolism.

[6] It belongs to family of aldose epimerases.

The two main amino acids in the enzyme active site are Glu 304, which acts as a Bronsted-Lowry base and abstracts a proton, and His 170, which acts as Bronsted-Lowry Acid to donate a proton to the galactose.
