The Biosynthesis of Thiamine I. ENZYMATIC FORMATION OF THIAMINE AND PHOSPHATE ESTERS OF THE PYRIMIDINE MOIETY OF THIAMINE*
The biosynthesis of thiamine appears to be accomplished with the initial formation of the pyrimidine and thiazole moieties by independent biosynthetic pathways, followed by a final step in which 2-methyl-4-amino-5-hydroxymethylpyrimidine and 4methyl-5-(/3-hydroxyethyl) thiazole are joined together to give thiamine. This conclusion was indicated originally from the observations that certain thia...

15 صفحه اولthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Thiamine-induced formation of the monopyrrole moiety of prodigiosin.
Thiamine stimulates the production of a red pigment, which is chromatographically and spectrophotometrically identical to prodigiosin, by growing cultures of Serratia marcescens mutant 9-3-3. This mutant is blocked in the formation of 2-methyl-3-amylpyrrole (MAP), the monopyrrole moiety of prodigiosin, but accumulates 4-methoxy-2,2,'-bipyrrole-5-carboxaldehyde (MBC) and can couple this compound...
