Biosynthesis of thiamin. Different biosynthetic routes of the thiazole moiety of thiamin in aerobic organisms and anaerobic organisms. 1987

K Tazuya, and M Morisaki, and K Yamada, and H Kumaoka, and K Saiki

The nitrogen atom of glycine was incorporated into the thiazole moiety of thiamin in the aerobic microorganisms Bacillus subtilis, Pseudomonas putida, Saccharomyces cerevisiae, Mucor racemosus, Neurospora crassa, and Emericella nidulans. It was not incorporated in the case of the facultative anaerobic microorganisms Escherichia coli and Enterobacter aerogenes, which, however, did incorporate the nitrogen atom of tyrosine. These results show that aerobic microorganisms and facultative anaerobic microorganisms have different biosynthetic pathways for the thiazole moiety of thiamin.

D001419 Bacteria One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive. Eubacteria
