Purification And Properties Of Bacterial Pyrimidine Nucleosidase , Lynn Merton Paege Jan 1951

Purification And Properties Of Bacterial Pyrimidine Nucleosidase , Lynn Merton Paege

Retrospective Theses and Dissertations

The metabolism of pyrimidine nucleosides was found to be similar to the dissimilation of purine nucleosides. Thus pyrimidine base is cleaved from the nucleoside and is accumulated. Ribose disappears from the reaction mixture; it is rapidly oxidised to carbon dioxide and water;Pyrimidine-bound ribose cannot be determined by the orcinol test of Mejbaum (1939). A modified orcinol reaction for this purpose was developed and used in the study of pyrimidine riboside metabolism;Pyrimidine nucleoside phosphorylase was isolated from extracts of E. coli and brought to a high degree of purity by fractional precipitation with ammonium sulfate and adsorption on and ...

Bacterial Utilization And Sequence Determination Of Peptides , Kenneth Frank Itschner Jan 1951

Bacterial Utilization And Sequence Determination Of Peptides , Kenneth Frank Itschner

Retrospective Theses and Dissertations

Preliminary experiments were performed to investigate the possibility of combining chemical blocking with microbiological assays in a method for determining terminal amino acids in peptides;A subtractive chromatographic procedure for determination of terminal amino acid residues in peptides is presented. Results are given for a total of nine dipeptides and one tripeptide. By employing selective cleavage of the treated tripeptide with dioxane-HCl the sequence of residues could be determined;The benzoyl derivatives of nine amino acids essential for L. arabinosus, of twelve amino acids essential for L. brevis , and one of ten amino acids essential for Strep. faecalis were tested ...
