5-(carboxymethylaminomethyl)-2-thiouridine, a new modified nucleoside found at the first letter position of the anticodon.
The structure of a modified uridine derivative which was detected at the first letter position of the anticodon of Bacillus subtilis tRNA1Lys was determined to be 5-(carboxymethylaminomethyl)-2-thiouridine. The determination was mainly based in this ultraviolet absorption spectra and mass spectrometric analysis of the trimethylsilyl derivative.
متن کاملmutant haloarchaeal isoleucine tRNAs a new modified nucleoside found in the anticodon wobble position of Identification and codon reading properties of 5-cyanomethyl uridine,
Most archaea and bacteria use a modified C in the anticodon wobble position of isoleucine tRNA to base pair with A but not with G of the mRNA. This allows the tRNA to read the isoleucine codon AUA without also reading the methionine codon AUG. To understand why a modified C, and not U or modified U, is used to base pair with A, we mutated the C34 in the anticodon of Haloarcula marismortui isole...
