Enzymes are enriched in bacterial essential genes. [PDF]

PLoS ONE, 2011
Essential genes, those indispensable for the survival of an organism, play a key role in the emerging field, synthetic biology. Characterization of functions encoded by essential genes not only has important practical implications, such as in identifying

A Eubacterial Origin for the Human tRNA Nucleotidyltransferase? [PDF]

, 2001
tRNA CCA-termini are generated and maintained by tRNA nucleotidyltransferases. Together with poly(A) polymerases and other enzymes they belong to the nucleotidyltransferase superfamily.

Identification of a novel aminoglycoside O-nucleotidyltransferase AadA33 in Providencia vermicola

Frontiers in Microbiology, 2022
A novel chromosome-encoded aminoglycoside O-nucleotidyltransferase AadA33 was identified in Providencia vermicola strain P13. The AadA33 shares the highest amino acid identity of 51.28% with the function characterized AadA31.

The Battle for Survival: The Role of RNA Non-Canonical Tails in the Virus–Host Interaction

Metabolites, 2023
Terminal nucleotidyltransferases (TENTs) could generate a ‘mixed tail’ or ‘U-rich tail’ consisting of different nucleotides at the 3′ end of RNA by non-templated nucleotide addition to protect or degrade cellular messenger RNA.

Terminal Uridylyltransferases TUT4/7 Regulate microRNA and mRNA Homeostasis

Cells, 2022
The terminal nucleotidyltransferases TUT4 and TUT7 (TUT4/7) regulate miRNA and mRNA stability by 3′ end uridylation. In humans, TUT4/7 polyuridylates both mRNA and pre-miRNA, leading to degradation by the U-specific exonuclease DIS3L2. We investigate the

AGO-bound mature miRNAs are oligouridylated by TUTs and subsequently degraded by DIS3L2

Nature Communications, 2020
3′ end of microRNAs binds to the PAZ domain of Argonaute (AGO) proteins. Here the authors show that terminal nucleotidyltransferases TUT4/7 and exonuclease DIS3L2 induce tailing and decay of 3’ end exposed-microRNAs in AGO PAZ mutant expressing- or ...

Origin of the Genetic Code Is Found at the Transition between a Thioester World of Peptides and the Phosphoester World of Polynucleotides

Life, 2019
The early metabolism arising in a Thioester world gave rise to amino acids and their simple peptides. The catalytic activity of these early simple peptides became instrumental in the transition from Thioester World to a Phosphate World.
