Question

enzymes that catalyse removal of groups from substrates by mechanisms other than hydrolysis leaving double bonds may have which one of following code numbers:
a. 4.1.1.1
b. 2.1.2.2
c. 6.1.3.2
d. 5.3.2.1​

Answer 1

Explanation:

Lyases enzymes catalyse the breakage of specific covalent bonds and removal of group with out hydrolysis producing double bonds or removal of double bonds by adding group,e.g., histidine decarboxylase that splits C−C bond of histidine,forming CO2 and histamine.
