aminoacyl trna synthetase造句

• This reaction, called tRNA charging, is catalyzed by aminoacyl tRNA synthetase.
• The enzyme aminoacyl tRNA synthetase " charges " the tRNA molecules with the correct amino acids.
• This aminoacyl-tRNA is produced in an ATP-dependent reaction carried out by an aminoacyl tRNA synthetase.
• This aminoacyl-tRNA precursor is produced in an ATP-dependent reaction carried out by an aminoacyl tRNA synthetase.
• Second, a novel pair of tRNA and aminoacyl tRNA synthetase are required, these are called the orthogonal set.
• Each tRNA is aminoacylated ( or " charged " ) with a specific amino acid by an aminoacyl tRNA synthetase.
• The combination of these two steps, both of which are catalyzed by aminoacyl tRNA synthetase, produces a charged tRNA that is ready to add amino acids to the growing polypeptide chain.
• For these codons to be useful, Aminoacyl tRNA synthetase has been created such that tRNA can code for the possibly synthetic amino acid to be coupled with its corresponding synthetic anti-codon.
• There is normally a single aminoacyl tRNA synthetase for each amino acid, despite the fact that there can be more than one tRNA, and more than one anticodon, for an amino acid.
• Extremely minor chemical changes such as the addition of a single methyl group to a binding partner can sometimes suffice to nearly eliminate binding; for example, the aminoacyl tRNA synthetase specific to the amino acid valine discriminates against the very similar side chain of the amino acid isoleucine.
• An "'aminoacyl tRNA synthetase "'( "'aaRS "') is an enzyme that attaches the appropriate amino acid onto its tRNA . It does so by catalyzing the esterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA . In humans, the 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases, one for each amino acid of the genetic code.
