Which enzyme is not used in a DNA repair pathway?

Alkyltransferase

DNA-N-glycosylases

Ligase

Photolyase

Glutathione S-transferase

Solution

Answer : The enzyme used in a DNA repair pathway is Glutathione S - transferase.

Alkyltranferase : Alkylated DNA is directly repaired by enzymes called alkyltranferases.

DNA - N - glycosylases : These are the family of enzymes involved in base excision repair of DNA.

Ligases : It facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays an important role in repairing single stranded breaks in duplex DNA.

Photolyases : photolyases are DNA repair enzymes that repair damage caused by exposure to ultraviolet light.

Glutathione S - transferase : These are also called as ligandins, metabolic isozymes best known for their ability to catalyze the conjugation of the reduced form of glutathione.
