The consequences of one-electron oxidation and one-electron reduction were studied for 4-aminopyrimidine (4APM), which displays prototropic tautomerism. Since experimental techniques are incapable of detecting less than 0.1% of minor tautomers, quantum-chemical calculations [DFT(B3LYP)/6-311+G(d,p)] were carried out for all possible tautomers

Ab initio calculations on the HF-SCF 6-31g* level were performed on tautomers as well as protonated and deprotonated species of thiamin. Aspects of the proton relay function of the 4'-aminopyrimidine ring in the thiamin catalysis were studied on model systems.

The mechanism of ThDP enzymes originates in the anionic (ylid) structure of the coenzyme. On the other hand, no ylid species (as permanently existing structure) could be detected by 13C2-NMR studies with PDC (yeast), when the cofactor binds to the
