Why ATP ended up being such a pivotal coenzyme, and not GTP, UTP, etc., is probably just a matter of chance. IV. 3. NucleotideMetabolism. Coenzyme A is biosyn- thesized in bacteria in nine steps. Although the chemical transformations of sugar nucleotides do not involve the atoms of the nucleotide itself, the sugar nucleotide molecule offers many potential groups for noncovalent interactions with enzymes; the free energy of binding contributes significantly to the catalytic activity of the enzyme (Chapter 8; see also p. 353). Pantoic acid is formed by the hydroxymethylation of ~-ketoisovalerate followed by reduction. If you continue browsing the site, you agree to the use of cookies on this website.
