An engineered variant of subtilisin BPN', termed subtiligase, which efficiently ligates esterified peptides in aqueous solution, was used for the complete synthesis of ribonuclease (RNase) A that contains unnatural catalytic residues. Fully active RNase A (124 residues long) was produced in milligram quantities by stepwise ligation of six esterified peptide fragments (each 12 to 30 residues lon...
An efficient and facile method for the synthesis of substituted imidazoles (10a-10g) has been reported by reacting aldehydes (1–7), benzil (8) ammonium acetate [9] in presence reuseable solid acid catalyst viz. Rice Husk Ash.SO3H (RHA.SO3H) at room temperature. The homogeneity compounds was confirmed melting point thin layer chromatography. All synthesized were characterized 1H NMR FTIR spectra...
DURING A STUDY on the metabolism of histidine in a child affected with histidinemia (Beauvais, P., and Humbel, R., to be published), we became interested in the chromatography of imidazoles. In this disease the urine contains numerous imidazoles: histidine and its metabolites, imidazole-pyruvic, imidazole-lactic and imidazole-acetic acids and N-acetylhistidine.’I developed a chromatographic met...
