The biosynthesis of the phage T4-coded proline and serine transfer RNA species proceeds through a precursor RNA containing both tRNA sequences. Neither tRNA sequence in the precursor RNA contains the 3'-terminal C-C-A common to all mature tRNAs. Seidman and McClain ((1975) Proc. Natl. Acad. Sci. U. S. A.

Biophysical and biochemical characterization of yeast tRNA nucleotidyltransferase variants [PDF]
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.

Post-transcriptional gene regulation mechanisms decide on cellular mRNA activities. Essential gatekeepers of post-transcriptional mRNA regulation are broadly conserved mRNA-modifying enzymes, such as cytoplasmic poly(A) polymerases (cytoPAPs).

The identity of the discriminator base has an impact on CCA addition [PDF]
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 ...

THE IDENTIFICATION OF NOVEL INORGANIC CARBON SENSITIVE ENZYMES [PDF]
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.

A LC-MS/MS-Based Approach to Studying the Saccharomyces cerevisiae Cca1 Protein [PDF]
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’

Characterization of Saccharomyces cerevisiae tRNA nucleotidyltransferase variants [PDF]
Yeast cells exhibit a temperature-sensitive phenotype at 37°C due to an ATP(CTP): tRNA nucleotidyltransferase variant containing a glutamate to phenylalanine substitution at position 189.

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

The role of arginine 204 in Candida glabrata tRNA nucleotidyltransferase [PDF]
The enzyme ATP(CTP):tRNA nucleotidyltransferase is required for protein synthesis in eukaryotes. It allows for the step-wise addition of a specific cytidine-cytidine-adenosine (CCA) sequence to the 3’ ends of tRNAs without the use of a nucleic acid ...

The role of arginine 244 in Candida glabrata tRNA nucleotidyltransferase [PDF]
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
