The biosynthesis of thiamine has been believed to be accomplished with the initial formation of the pyrimidine and thiazole moieties by independent routes, followed by a final step in which pyrimidine and thiazole are jointed together to form thiamine. Recently, Nose (1-3), Brown (4-7), and Leder (8, 9) separated the enzyme system from cell-free extracts of bakers' yeast which is capable of syn...

The complete amino acid sequence of chicken heart cytochrome c has been established. This primary structure is typically that of a “mammalian-type” cytochrome c showing the characteristic groupings of hydrophobic and basic residues, and, like the other cytochromes c from vertebrate species, has an acetylated amino-terminal residue. Chicken heart cytochrome c differs from the horse, beef, human,...

In order to contribute to the description of sourdough LAB composition, MiSeq sequencing and qPCR methods were performed in association with cultural methods. A panel of 16 French organic bakers and farmer-bakers were selected for this work. The lactic acid bacteria (LAB) diversity of their organic sourdoughs was investigated quantitatively and qualitatively combining (i) Lactobacillus sanfranc...

Dihydrouridine residues in bakers’ yeast transfer RNA were reductively cleaved with sodium borohydride. The amino acid acceptor activity of three species of transfer RNA and the ribosoma binding of one species of transfer RNA were determined for these modified transfer RNAs. The data indicate that the reductive cleavage of the dihydrouridine residues in these transfer RNAs has no effect upon th...
