Bacterial toxin–antitoxin (TA) systems (or “addiction modules”) typically facilitate cell survival
during intervals of stress by inducing a state of reversible growth arrest. However, upon …

SlyD is a putative folding helper protein from the Escherichia coli cytosol, which consists of
an N-terminal prolyl isomerase domain of the FKBP type and a presumably unstructured C …

It is impossible to predict which pathway, direct glutaminylation of tRNAGln or tRNA-
dependent transamidation of glutamyl-tRNAGln, generates mitochondrial glutaminyl …

Cyclic peptides are important natural products and hold great promise for the identification of
new bioactive molecules. The split‐intein‐mediated SICLOPPS technology provides a …

Chemoselective and regioselective chemical protein labeling is of great importance, yet no
current technique is sufficiently general and simple to perform. Protein trans‐splicing by split …

As part of a study to purify the internal domain of HER2 (ICD) from recombinant expression,
through metal immobilised affinity chromatography (IMAC), we encountered a contaminant …

Transition metals are common components of cellular proteins and the detailed study of
metalloproteins necessitates the identification and quantification of bound metal ions …

tmRNA (transfer messenger RNA) is a unique molecule used by all bacteria to rescue
stalled ribosomes and to mark unfinished peptides with a specific degradation signal …

RapA, a prokaryotic member of the SWI/SNF protein superfamily, is an integral part of the
RNA polymerase transcription complex. RapA's function and catalytic mechanism have …

Staphylococcal enterotoxins (SEs) are the second most common causal agents of food
