Abstract:
N6-methyladenosine (m(6)A) is ubiquitously present in the RNA of living organisms from Escherichia coli to humans. Methyltransferases that catalyze adenosine methylation are drastically different in specificity from modification of single residues in bacterial ribosomal or transfer RNA to modification of thousands of residues spread among eukaryotic mRNA. Interactions that are formed by m(6)A residues range from RNA-RNA tertiary contacts to RNA-protein recognition. Consequences of the modification loss might vary from nearly negligible to complete reprogramming of regulatory pathways and lethality. In this review, we summarized current knowledge on enzymes that introduce m(6)A modification, ways to detect m(6)A presence in RNA and the functional role of this modification everywhere it is present, from bacteria to humans.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
