[14] Stereochemistry of selected phosphotransferases and nucleotidyltransferases
1982Publisher Summary In recognition of the experimental imperatives for carrying out stereochemical analyses of chemical reactions, this chapter deals with the methodologies of such research. It describes methods for synthesizing chirally substituted phosphorothioate analogs of biological phosphates.

Inhibition of RNA nucleotidyltransferase by 6-azauridine triphosphate
Biochimica et Biophysica Acta, 1963ABS>Escherichia coli RNA polymerase was prepared, and the synthetic reaction was assayed by the method of Chamberlin and Berg. Phosphorus-32-labeled uridine triphosphate (UTP) was used as the proximally labeled nucleotide. The pyrophosphate-nucleoside triphosphate exchange reaction dependent on crab- daT(deoxyadenylate and thymidylate) (or daT ...

Study of the Escherichia coli tRNA nucleotidyltransferase
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1974Abstract A complex between Escherichia coli tRNA nucleotidyltransferase and tRNA has been isolated by centrifugation in a glycerol gradient (sedimentation constant 5.3 S). The complex is dissociated in the presence of ethylenediamine tetraacetate or high salt concentrations. The apparent K m of the enzyme for E.

Phylogeny and Evolution of RNA 3′-Nucleotidyltransferases in Bacteria
Journal of Molecular Evolution, 2019The tRNA nucleotidyltransferases and poly(A) polymerases belong to a superfamily of nucleotidyltransferases. The amino acid sequences of a number of bacterial tRNA nucleotidyltransferases and poly(A) polymerases have been used to construct a rooted, neighbor-joining phylogenetic tree.

tRNA nucleotidyltransferases: ancient catalysts with an unusual mechanism of polymerization
Cellular and Molecular Life Sciences, 2010RNA polymerases are important enzymes involved in the realization of the genetic information encoded in the genome. Thereby, DNA sequences are used as templates to synthesize all types of RNA. Besides these classical polymerases, there exists another group of RNA polymerizing enzymes that do not depend on nucleic acid templates.

Subcellular specialization of multifaceted 3′end modifying nucleotidyltransferases
Current Opinion in Cell Biology, 2012While canonical 3'end modifications of mRNAs or tRNAs are well established, recent technological advances in RNA analysis have given us a glimpse of how widespread other types of distinctive 3'end modifications appear to be. Next to alternative nuclear or cytoplasmic polyadenylation mechanisms, evidence accumulated for a variety of 3'end mono ...

Ribonucleases, ?RNA Nucleotidyltransferase, and the 3' Processing of ?RNA
1990Publisher 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 ...

[58] Rabbit liver tRNA nucleotidyltransferase
1974Publisher Summary This chapter describes the procedures for the purification of the enzyme from Escherichia coli , and rabbit liver. This procedure yields a preparation of the enzyme from rabbit liver that is homogeneous and about 30,000-fold purified.
