THE PARTIAL SYNTHESIS OF RIBOSE NUCLEOTIDES

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Synthesis in the study of nucleotides.

Enzymatic synthesis of purine nucleotides.

The demonstration of a pathway of pyrimidine nucleotide synthesis in which PRPP’ is a key intermediate (1, 2) prompted a study to determine whether the same type of reaction mechanism might apply to the synthesis of purine nucleotides. In a preliminary note the condensation of adenine with PRPP to yield A5P was reported (3). Subsequent work has established the existence of enzymes in yeast whic...

Pyrrolopyrimidine nucleotides and protein synthesis.

The interaction of amino pyrrolopyrimidine nucleotides with enzymes catalyzing different steps in the reaction sequence leading to the incorporation of amino acids into polypeptides has been studied. None of the analogue nucleotides could function as the energy source for activation of amino acids or esterification of transfer RNA (tRNA) by mammalian or bacterial enzymes. Toyocamycin S’-triphos...
