Ligases is a class of enzymes responsible for catalysing the linking together of two compounds.Which of the following bonds is not catalysed by it?
A
C-C
B
P-O
C
C-O
D
C-N
Answer
C-C
Explanation
Solution
Ligases catalyze the formation of bonds between carbon and other atoms like oxygen, nitrogen, sulfur, orphosphorus (C-O, C-N, C-S, C-P). They do not directly catalyze the formation of C-C bonds. Although some ligase-catalyzed reactions might indirectly lead to C-C bond formation in subsequent steps, the direct joining of two carbon atoms isn’t a primary function of ligases.
