DOI: 10.1002/cbic.202200281
Abstract: The Picornavirales include viruses that infect vertebrates, insects, and plants. It was believed that they pack only their genomic mRNA in the particles; thus, we envisaged these viruses as excellent model systems for studies of… read more here.

DOI: 10.1002/humu.23870
Abstract: The wobble position in the anticodon loop of transfer ribonucleic acid (tRNA) is subject to numerous posttranscriptional modifications. In particular, thiolation of the wobble uridine has been shown to play an important role in codon‐anticodon… read more here.

DOI: 10.1002/pro.4319
Abstract: N6‐methyladenosine (m6A), widely distributed in both coding and noncoding RNAs, regulates the epigenetic signals and RNA metabolism in eukaryotes. Although this posttranscriptional modification is frequently observed in messenger and ribosomal RNA, it is relatively rare… read more here.

DOI: 10.1002/wrna.1564
Abstract: Aminoacyl tRNA synthetases (aaRS) are well studied for their roles in tRNA charging with cognate amino acid. Nevertheless, numerous lines of evidence indicate that these proteins have roles other than tRNA charging. These include coordination… read more here.

DOI: 10.1007/s12104-018-9849-9
Abstract: Bacterial tRNA (guanine37-N1)-methyltransferase (TrmD) is an important antibacterial target due to its essential role in translation. TrmD has two domains connected with a flexible linker. The N-terminal domain (NTD) of TrmD contains the S-adenosyl-l-methionine (SAM)… read more here.

DOI: 10.1016/j.freeradbiomed.2017.10.297
Abstract: We recently reported the production of a large quantity of reactive persulfides including cysteine hydropersulfide (CysSSH) in both prokaryotes and eukaryotes. Also, these reactive persulfides reportedly show critical functions for regulation of redox signaling. Currently,… read more here.

DOI: 10.1016/j.jmb.2020.08.003
Abstract: One-carbon metabolism produces methionine and N10-formyl-tetrahydrofolate (N10-fTHF) required for aminoacylation and formylation of initiator tRNA (i-tRNA), respectively. In Escherichia coli, N10-fTHF is made from 5, 10-methylene-THF by a two-step reaction using 5,10-methylene-THF dehydrogenase/cyclohydrolase (FolD). The… read more here.
