HemK NTD cotranslational folding starts within the ribosome exit tunnel upon N-terminal helix synthesis and proceeds sequentially through a series of intermediates becoming less dynamic as the nascent chain grows.
An unusual molecular mechanism has been revealed based on ultrastable histidine cluster co-aggregation underlying feedback control of an ancient cell communication pathway.

SCCmec genomic islands encode a novel primase-helicase pair in which priming ability is conferred upon an A-family DNA polymerase domain by a novel protein cofactor.
Light-sensitive allosteric switch module, a broadly applicable protein engineering method, is used for the regulation of protein activity with tight temporal control and spatial precision.
Chemical modifications near the tRNA anticodon and specific mRNA–tRNA pairs combine to control the ribosomal three-nucleotide mRNA reading frame, essential for the sequential addition of amino acids into polypeptide chains.
