Phylogeny and Evolution of RNA 3′-Nucleotidyltransferases in Bacteria

Journal of Molecular Evolution, 2019
The 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.

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

Subcellular specialization of multifaceted 3′end modifying nucleotidyltransferases

open access: yesCurrent Opinion in Cell Biology, 2012
While 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.

[14] Stereochemistry of selected phosphotransferases and nucleotidyltransferases

open access: yes, 1982
Publisher 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.

Schizosaccharomyces pombe contains separate CC- and A-adding tRNA nucleotidyltransferases

Biochemical and Biophysical Research Communications, 2019
A specific cytidine-cytidine-adenosine (CCA) sequence is required at the 3'-terminus of all functional tRNAs. This sequence is added during tRNA maturation or repair by tRNA nucleotidyltransferase enzymes.

Transfer RNA nucleotidyltransferase

open access: yes, 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 ...
