COG4849 is a novel family of nucleotidyltransferases

Journal of Molecular Recognition, 2005
Only a minority of currently known protein families is characterized structurally. This makes homology-based structure modeling an essential instrument that can be viewed as the first approximation to experimental determination of protein structure. Using sequence similarity searches, we detected a distant similarity between a family of uncharacterized

Plant tRNA nucleotidyltransferase

Planta, 1978
A method for purification of tRNA nucleotidyltransferase from Lupinus luteus L. seeds on a preparative scale is presented. This involved ammonium sulfate fractionation and chromatography on DEAE-cellulose, hydroxylapatite, and QAE-Sephadex A-50. The final enzyme prepartion was apparently homogeneous and a 2000-fold purification was achieved.

Induction of DNA nucleotidyltransferase by the shope fibroma virus

Virology, 1967
Abstract DNA nucleotidyltransferase activity is increased in extracts of rabbit kidney cells infected by the Shope fibroma virus and assayed under various conditions. Determination of the optimal conditions for assay shows that there are two separate activities.

Transfer RNA nucleotidyltransferase

1990
Publisher Summary All tRNA molecules contain, at the 3′ terminus, the identical-CCA sequence that is required for their acceptor and transfer functions. In prokaryotic cells, no discrete pattern has emerged. In laboratory strains of Escherichia coli , all tRNA genes sequenced encode the -CCA sequence, and mutant strains devoid of tRNA ...

DNA nucleotidyltransferase activity of the developing rat brain

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1970
Abstract DNA polymerase (deoxynucleoside triphosphate: DNA deoxynucleotidyltransferase, EC 2.7.7.7) activity in soluble extracts from developing rat brain has been studied. The DNA polymerase from infant rat brain required the presence of template DNA, Mg2+ and all four deoxynucleoside triphosphates.

7 tRNA Nucleotidyltransferase

1982
Publisher Summary ATP(CTP)-tRNA nucleotidyltransferase catalyzes the incorporation of AMP and CMP residues into tRNA molecules from which all, or part, of the 3 terminal trinucleotide sequence, –C–C–A, has been removed. tRNA nucleotidyltransferase activity has been identified in a wide variety of organisms including mammals, birds, amphibians ...
