EC 5.1 Racemases and Epimerases

EC 5.1 subclass definition

The EC 5.1 subclass contains Racemases and Epimerases - Isomerases that catalyze racemization or epimerization of chiral centres in molecules. Further classification is based on type of substrates utilized during the catalytic act.

Further classification of EC 5.1 subclass

This classification is based on type of substrates subjected to epimerization or racemization.

EC 5.1.1 - Substrates are amino acids and derivatives
EC 5.1.2 - Substrates are hydroxy acids and derivatives
EC 5.1.3 - Substrates are carbohydrates and derivatives
EC 5.1.99 - Substrates are all other compaunds
