We have been aware of the existence of knotted proteins for over 30 years—but it is hard to predict what is the most complicated knot that can be formed in proteins. Here, we show new and the most complex knotted topologies recorded to date—doubl

The genomes of intracellular symbiotic or pathogenic bacteria, such as of Buchnera, Mycoplasma, and Rickettsia, are typically smaller compared with their free-living counterparts. Here we showed that noncoding RNA (ncRNA) families, which are conserve

The 5′-cap structure, characteristic for RNA polymerase II-transcribed RNAs, plays important roles in RNA metabolism. In humans, RNA cap formation includes post-transcriptional modification of the first transcribed nucleotide by RNA cap1 methyltran

In addition to mRNAs whose primary function is transmission of genetic information from DNA to proteins, numerous other classes of RNA molecules exist, which are involved in a variety of functions, such as catalyzing biochemical reactions or performi

In erythromycin–resistant bacteria, the N6 position of A2058 in 23S rRNA is mono– or dimethylated by Erm family methyltransferases. This modification results in cross–resistance to macrolides, lincosamides and streptogramin B. Most inhibitors o

The 5' cap of human messenger RNA consists of an inverted 7-methylguanosine linked to the first transcribed nucleotide by a unique 5'-5' triphosphate bond followed by 2'-O-ribose methylation of the first and often the second transcribed nucleotides,
