ADAM17 (where ADAM is 'a disintegrin and metalloproteinase') can rapidly modulate cell-surface signalling events by the proteolytic release of soluble forms of proligands for cellular receptors. Many regulatory pathways affect the ADAM17 sheddase activity, but the mechanisms for the activation are still not clear. We have utilized a cell-based ADAM17 assay to show that thiol isomerases, specifi...

OBJECTIVE Staphylococcus aureus can induce platelet aggregation. The rapidity and degree of this correlates with the severity of disseminated intravascular coagulation, and depends on platelet peptidoglycans. Surface-located thiol isomerases play an important role in platelet activation. The staphylococcal extracellular adherence protein (Eap) functions as an adhesin for host plasma proteins. T...
The cis/trans isomerization of peptide bonds before proline (prolyl bonds) is a rate-limiting step in many protein folding reactions, and it is used to switch between alternate functional states of folded proteins. Several prolyl isomerases of the FK506-binding protein family, such as trigger factor, SlyD, and FkpA, contain chaperone domains and are assumed to assist protein folding in vivo. Th...
Prolyl isomerases comprise three main protein families totalling over thirty mammalian genes, and several hundred orthologues across the biological domains, with a very broad spectrum of physiological functions and disease implications. Potent small molecule inhibitors exist for members of the three main mammalian families (cyclophilins, FKBPs and parvulins),. but, until recently, these protein...
Immunophilins, including FK506-binding proteins (FKBPs), are protein chaperones with peptidyl-prolyl isomerase (PPIase) activity. Initially identified as pharmacological receptors for immunosuppressants to regulate immune responses via isomerase-independent mechanisms, FKBPs are most highly expressed in the nervous system, where their physiological function as isomerases remains unknown. We dem...
Rare arginine codons AGA and AGG affect the heterologous expression of proteins in Eschericha coli. The tRNAs necessary for protein synthesis are scarce in E. coli strain BL21(DE3) pLysS and plentiful in strain BL21(DE3) CodonPlus -RIL. We evaluated in both bacterial strains the effect of these rare codons on the expression of triosephosphate isomerases from 7 different species, whose sequences...
