Three B. subitilis serine tRNAs were sequenced including modified nucleosides. All the serine tRNAs contained 1-methyl-adenosine in the D-loop. As other characteristic modified nucleosides, 5-methoxyuridine was found in the first letter of the anticodon in the tRNA(UGA).

In Bacillus subtilis, four codons, CCU, CCC, CCA, and CCG, are used for proline. There exists, however, only one proline-specific tRNA having the anticodon mo(5)UGG. Here, we found that this tRNA(Pro)(mo(5)UGG) can read not only the codons CCA, CCG and

The encapsulation of mRNA in nanosystems as gene vaccines for immunotherapy purposes has experienced an exponential increase in recent years. Despite the many advantages envisaged within these approaches, their application in clinical treatments is still limited due to safety issues.

A valine tRNA was purified from Bacillus subtilis W168 by a combined use of several column chromatographic systems. The nucleotide sequence was determined to be pG-G-A-G-G-A-U-U-A-G-C-U-C-A-G-C-D-G-G-G-A-G-A-G-C-A-U-C--G-C-C-U-mo5U-A-C-m6-A -A-G-C-A-G-A-G-G-m7G-U-C-G-G-C-G-G-T-psi-C-G-A-G-C-C-C-G-U-C-A-U-C-C-U-C-C-A-C- C-AOH with the main use of of non-labeled tRNA and with the subsidiary
