The Incorporation of Radioactive Sulfur into Thiamine by Saccharomyces Cerevisiae.
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...
متن کاملEffect of nikethamide (coramine) on incorporation of radioactive phosphate into rat liver deoxypentosenucleic acid.
Examples of substances reported to stimulate liver growth are few. Coramine (nikethamide, or diethylnicotinamide) causes an increase in the absolute, fat-free weight of the liver of the young rat and would appear to qualify as one of these. The effect was first noted by Coulson and Brazda in 1947 (5) in 45-50-gm. rats fed 1.0 per cent levels of Coramine in a high protein diet. It was an un expe...
متن کاملIncorporation of radioactive phosphate into the nucleic acids of brain slices.
The unequivocal incorporation of radioactive phosphate (32p) into the nucleic acids of brain slices has not as yet been demonstrated. Because of the great interest in the nucleic acids of the nervous system aroused by the work of Caspersson (1947) and Hyden (1943, 1947), it was decided to investigate the possible incorporation of 32p into the pentosenucleic acid (PNA) and deoxypentosenucleic ac...
متن کاملIncorporation of radioactive phosphate into nucleic acids of regenerating rat liver.
It has been repeatedly demonstrated in tracer experiments that deoxypentosenucleic acid (DNA) is biochemically inert in tissues where little or no cell division occurs (1, 10, 192, 17). However, in proliferating tissues, such as tumors (92,928) and regenerating liver (5, 6, 8, 14), labeled precursors are rapidly incorporated into DNA. These obser vations have led to the concept that DNA is synt...
متن کاملLA Phosphate Incorporation in Brain
To test this hypothesis, we have investigated the incorporation of radioactive inorganic phosphate into these phospholipids by rabbit brain slices. If the biosynthesis proceeds as formulated, I --f II + III, the following results can be predicted. Before equilibration of the labeled phosphorus, the phosphate groups in position 4 of II and positions 4 and 5 of 111 must have a higher radioactivit...
