Thiamine (vitamin B1) is crucial for life and plays a central role in metabolism. It contains thiazole and pyrimidine moieties that are constructed independently and then assembled together to generate thiamine phosphate. The study of the thiazole moiety is relatively clear, but deciphering the mechanistic enzymology of thiamine pyrimidine is more difficult. This review aims to summarize the recent research progress on ThiC rearrangement, mainly including the mechanism, related enzymes, and genes involved in the rearrangement.
Keywords: SAM enzyme; ThiC; nucleosides; rearrangement; thiamine.
