Aminoacylation, the attachment of an amino acid to a tRNA, is typically a two-step process catalyzed by aminoacyl-tRNA synthetases (aaRSs). The first step, termed “activation”, is the formation of an aminoacyl-AMP (aminoacyl-adenylate) on the enzyme through the hydrolysis of adenosine tripho...

Amino Acid Transfer RNA Ligase In subject area: Medicine and Dentistry Aminoacyl-tRNA synthetases (aaRSs) are the enzymes responsible for the esterification of a specific amino acid, or its precursor, to its compatible cognate tRNA to form aminoacyl-tRNAs. From: Trends in Parasitology, 2011 About...
What term is used for a non-protein organic molecule that is required by some enzymes in order to catalyze a reaction on a substrate? a) prosthetic group b) cofactor c) co-enzyme d) modulator How does an amino acid become attached to a tRNA m...
During translation errors of aminoacylation are corrected in editing reactions which ensure that an amino acid is stably attached to its corresponding transfer RNA (tRNA). Previous studies have not shown whether the tRNA nucleotides needed for effecting translational editing are the same as or distinct...
tRNA has the following sequence in its anticodon: 5'-GAA-3'. Which amino acid should be attached to this tRNA? The three base pairs of mRNA are called ___. (a) amino acid (b) codon (c) anticodon (d) nucleotide. How many amino acids were coded for the mRNA? With which...

while fluorescence assays were developed and conducted to verify the in silico results and elucidate a 15-amino acid signature sequence (R-W-Q/N-H-X2-F-Pho-X-G/A-W-R-X2-G, where X can be most amino acids, and Pho is hydrophobic) that recognized the tRNA's fully modified anticodon...
Similarly, Pol III occupancy of amino acid isotypes is almost invariant among transcriptionally and evolutionarily diverse tissues in mouse. Thus, synthesis of functional tRNA isotypes has been highly constrained, although the usage of individual tRNA genes has evolved rapidly. This is a preview of ...
A tRNA is charged with the amino acid phenylalanine(a) At what end of tRNA is this amino acid attached?(b) What is the mRNA codon that coded for phenylalanine?(c) What is its anticodon?(d) Name the enzyme responsible for this attachment. View Solution Q2 The a...
