Purification of transfer-RNA-nucleotidyltransferase from E. Coli B

Biochemical and Biophysical Research Communications, 1970
Abstract Transfer-RNA-nucleotidyltransferase has been purified 1400-fold from E. coli B by liquid polymer phase fractionation and chromatography on DEAE-cellulose, hydroxylapatite, and QAE-Sephadex. The final preparation contains no detectable RNase I, RNase II, polynucleotide phosphorylase, ATPase, CTPase, or any of the aminoacyl-tRNA ...

Ribonucleases, ?RNA Nucleotidyltransferase, and the 3' Processing of ?RNA

, 1990
Publisher Summary This chapter describes 3’ maturation and repair, with particular emphasis on the ribonucleases and tRNA nucleotidyltransferase, the enzymes that participate in these processes. All tRNA molecules are synthesized initially as tRNA precursors containing additional residues at their 5’ and 3‘ termini that must be removed to generate ...

Identification of a tRNA nucleotidyltransferase and its substrates in virions of avian RNA tumor viruses

Virology, 1974
Abstract Purified preparations of avian RNA tumor viruses contain a nucleotidyltransferase which catalyzes the addition of adenosine monophosphate and cytosine monophosphate at the 3′-end of certain transfer RNAs, probably in the sequence pCpCpAoh.

The polynucleotide ligase and RNA capping enzyme superfamily of covalent nucleotidyltransferases

Current Opinion in Structural Biology, 2004
ATP- and NAD(+)-dependent DNA ligases, ATP-dependent RNA ligases and GTP-dependent mRNA capping enzymes comprise a superfamily of proteins that catalyze nucleotidyl transfer to polynucleotide 5' ends via covalent enzyme-(lysyl-N)-NMP intermediates. The superfamily is defined by five peptide motifs that line the nucleotide-binding pocket and contribute ...

Transfer RNA metabolism in Escherichia coli cells deficient in tRNA nucleotidyltransferase

Journal of Molecular Biology, 1977
We have investigated the role of tRNA nucleotidyltransferase in transfer RNA metabolism using mutants ( cca mutants) of Escherichia coli deficient in this enzyme. Extracts of the most defective strain contained cca mutation into a variety of genetic backgrounds. However, tRNA from stationary phase cells was somewhat more defective.
