Question

Which of the following is an example of regeneration of the derivatized coenzymes by enzymic means?

(a) Formate dehydrogenase

(b) Exocyclic N6-amino nitrogen of the adenine moiety

(c) Dextrans

(d) Polyethylene glycol

This question was posed to me in an interview.

My question is from Future Prospects in division Enzyme Technology Future Prospects of Enzyme Technology

Answer 1

Right option is (a) Formate dehydrogenase

To explain I would say: The regeneration of the derivatized coenzymes by enzymic means is advantageous because of its high specificity. Enzymic processes utilizes cheap substrates and readily available enzymes. They also give non-interfering and easily separated products. Formate dehydrogenase and acetate kinase are useful examples of this.
