<p>3-Hydroxyisonicotinaldehyde is a disulfide bond that plays an important role in enzyme catalysis. The active site of the enzyme, which contains a nucleophilic attack on the electrophilic carbon atom, is composed of two cysteine residues with their sulfhydryl group (-SH) bonded to each other through a disulfide bond. This bond can be broken by either an acidic environment or protonation. In the absence of these conditions, the -SH groups are coordinated to metal ions and form a complex. The hydroxyl group (-OH) on one cysteine residue can coordinate to the nitrogen atom on the other cysteine residue and form tautomers. These tautomers correspond to two different configurations of the molecule: one where both sulfur atoms are in a trans configuration (tautomer A), and one where they are in a cis configuration (tautomer B).
