Expression, Enzymatic Activities and Subcellular Localization of Hepatitis E Virus and Semliki Forest Virus Replicase Proteins [PDF]
, 2006 Viruses are submicroscopic, infectious agents that are obligate intracellular parasites. They adopt various types of strategies for their parasitic replication and proliferation in infected cells.

Biophysical and biochemical characterization of yeast tRNA nucleotidyltransferase variants [PDF]
, 2017 The enzyme ATP(CTP):tRNA-specific tRNA nucleotidyltransferase adds cytidine-cytidine-adenosine (CCA) to the 3’ end of eukaryotic tRNAs during their maturation. This CCA sequence plays a vital role in aminoacylation and hence in protein synthesis.

EVALUATION OF ANTIBIOTIC RESISTANCE PROFILES OF HALOBACTERIA ISOLATED FROM THE FOOD CHAIN [PDF]
, 2017 L’insorgenza e la diffusione dell’antibiotico resistenza sta diventando un problema a livello mondiale. Molti sono gli ambienti in cui può avvenire tale diffusione, ma una delle principali vie di trasmissione passa attraverso la catena alimentare ...

The identity of the discriminator base has an impact on CCA addition [PDF]
, 2015 CCA-adding enzymes synthesize and maintain the C-C-A sequence at the tRNA 3''-end, generating the attachment site for amino acids. While tRNAs are the most prominent substrates for this polymerase, CCA additions on non-tRNA transcripts are described as ...

A LC-MS/MS-Based Approach to Studying the Saccharomyces cerevisiae Cca1 Protein [PDF]
, 2018 The enzyme ATP (CTP): tRNA-specific tRNA nucleotidyltransferase (tRNA-NT) is an essential enzyme in eukaryotes and some prokaryotes and plays a critical role in tRNA maturation. This enzyme is responsible for the addition of AMP and CMP residues to the 3’

THE IDENTIFICATION OF NOVEL INORGANIC CARBON SENSITIVE ENZYMES [PDF]
, 2010 Adenylyl cyclase catalyses the formation of the second messenger adenosine-3’, 5’-monophosphate from adenosine triphosphate, and is involved in a number of diverse signalling pathways in eukaryotes and prokaryotes.

Divergent Evolution of Eukaryotic CC- and A-Adding Enzymes [PDF]
Synthesis of the CCA end of essential tRNAs is performed either by CCA-adding enzymes or as a collaboration between enzymes restricted to CC- and A-incorporation. While the occurrence of such tRNA nucleotidyltransferases with partial activities seemed to

Characterization of temperature-sensitivity and its intragenic suppression in Saccharomyces cerevisiae tRNA nucleotidyltransferase mutants [PDF]
, 2011 ATP:CTP-specific tRNA nucleotidyltransferase enzymes catalyze the stepwise addition of one CMP, a second CMP, and finally an AMP as needed to generate the functional 3’ termini of tRNA molecules.

The role of arginine 244 in Candida glabrata tRNA nucleotidyltransferase [PDF]
, 2009 The enzyme ATP(CTP):tRNA nucleotidyltransferase is essential in eukaryotes to allow tRNAs to participate in protein synthesis. It adds a specific cytidine-cytidine-adenosine (CCA) sequence to generate positions 74, 75, and 76 at the 3' ends of tRNAs in a
