Item 23 Part A Which of the following is the sequence of steps followed by biotin-dependent enzymes, as listed below? l. Transfer of the carboxyl group from carboxybiotin to the substrate II. Activation of bicarbonate by ATP Ill. Formation of carboxybiotin II, III, O I, II, III O III, II, O II, I, III O I, III, II

Explanation / Answer

The correct steps are

1.Formation of carboxybiotin

2.Activation of bicarbonate by ATP

3.Transfer of the carboxyl group from carboxybiotin to the substrate.
