Secretion of recombinant enzymes to extracellular milieu is important for enhanced degradation of toxic pollutants since the substrates are often inadequately taken up by cells. The twin-arginine translocation (Tat) pathway is a secretion mechanism for the transport of folded proteins across the cytoplasmic membrane of bacteria. Notably, two substr...
Background The gastrointestinal tract microbiota (GTM) of mammals is a complex microbial consortium, the composition and activities of which influences mucosal development, immunity, nutrition and drug metabolism. It remains unclear whether the composition of the dominant GTM is conserved within animals of the same strain and whether stable GTMs ar...
To infect their mammalian hosts, Fasciola hepatica larvae must penetrate and traverse the intestinal wall of the duodenum, move through the peritoneum, and penetrate the liver. After migrating through and feeding on the liver, causing extensive tissue damage, the parasites move to their final niche in the bile ducts where they mature and produce eg...
The role of PIP(2) in pancreatic beta cell function was examined here using the beta cell line MIN6B1. Blocking PIP(2) with PH-PLC-GFP or PIP5KIgamma RNAi did not impact on glucose-stimulated secretion although susceptibility to apoptosis was increased. Over-expression of PIP5KIgamma improved cell survival and inhibited secretion with accumulation ...
The large-scale analysis of protein complexes is an emerging challenge in the field of proteomics. Currently, there are few methods available for the fractionation of protein complexes that are compatible with downstream proteomic techniques. Here, we describe the technique of blue native continuous elution electrophoresis (BN-CEE). It combines the...
Plasmodium falciparum parasites are responsible for the major global disease malaria, which results in > 2 million deaths each year. With the rise of drug-resistant malarial parasites, novel drug targets and lead compounds are urgently required for the development of new therapeutic strategies. Here, we address this important problem by targeting t...

EAK(16) (AEAEAKAKAEAKAEAK) belongs to a novel class of self-assembling peptides, which is being investigated in research and industry. SUMO belongs to the ubiquitin class of proteins and is a promising fusion partner currently in use. In this study, EAK(16) peptide fusions with hexa-histidine tagged SUMO have been constructed using Escherichia coli...

BackgroundSingle chain Fvs (scFvs) are widely applied in research, diagnostics and therapeutic settings. Display and selection from combinatorial libraries is the main route to their discovery and many factors influence the success of this process. They exhibit low thermodynamic stability, resulting in low levels of premature cytosolic folding or a...

Intrinsically disordered proteins are thought to undergo coupled binding and folding upon interaction with their folded partners. In this study, we investigate whether binding of the intrinsically disordered T cell receptor zeta cytoplasmic tail to the well-folded simian immunodeficiency virus Nef core domain is accompanied by a disorder-to-order t...
