Background. There is a need for alternative oral phosphate binders. In-vitro studies showed that iron(III)oxide-hydroxide-modified cross-linked dextran is a promising, insoluble phosphate-binding agent. The present study was designed to assess its in

Activation of aminoacids for proteinbiosynthesis is not absolutely specific. With tRNA modified at the 3' end we were able to show, that valine misactivated by isoleucyl-tRNA synthetase is transferred to tRNA(I1e). Val-tRNA(I1e) is then hydrolyzed by

TRNA-Phe species from baker's yeast modified at the 3'-terminus in many cases are phenylalanylatable substrates. Out of several tRNA-Phe species possessing a modified 3'-end that cannot be phenylalanylated, only two, tRNA-Phe-C-C-2'dA and the tRNA-Ph

The cytoplasmic leucyl-tRNA synthetases of Neurospora crassa wild type (grown at 37 degrees C) and mutant (grown at 28 degrees C) were purified approximately 1770-fold and 1440-fold respectively. Additional enzyme preparations were carried out with m

AMP can be oxidized to AMP-1- N -oxide by monoperphthalic acid at pH 7.0 and 20°C in aqueous buffer on the monomer as well as on the polymer level. No reaction occurs if nitrogen 1 is protected, e.g., by hydrogen bonding. The reaction is used for st
