A Missing Enzyme in Thiamin Thiazole Biosynthesis: Identification of TenI as a Thiazole Tautomerase [PDF]

Journal of the American Chemical Society, 2011
In many bacteria tenI is found clustered with genes involved in thiamin thiazole biosynthesis. However, while TenI shows high sequence similarity with thiamin phosphate synthase, the purified protein has no thiamin phosphate synthase activity, and the role of this enzyme in thiamin biosynthesis remains unknown.

Thiazoles in glycosylation reactions: Novel synthesis of thiazole thioglycosides

Heteroatom Chemistry, 2017
AbstractThis research reports a novel method for synthesizing new thiazole thioglycosides. This series of thiazole thioglycosides were designed by the reaction of potassium cyanocarbonimidodithioate 2 with benzoyl acetonitrile 3a and ethyl bromoacetate 3b in the presence of ethanol‐KOH to give the corresponding potassium 4‐amino‐5‐substituted‐thiazole ...
