The microaerophilic food-borne pathogen Campylobacter jejuni uses complex cytochrome-rich respiratory chains for growth and host colonization. Cytochrome c biogenesis requires haem ligation to reduced apocytochrome cysteines, catalysed by the cytochrome c synthase, CcsBA. While ccsBA could not be deleted, we showed that the thiol reductase DsbD and the CcsX homologue Cj1207 are involved in, but...

Tuberculosis (TB) is a devastating disease that affects humans and many animal species. In humans, TB is mainly caused by Mycobacterium tuberculosis, whereas most cases in cattle are caused by Mycobacterium bovis. However, M. bovis can also cause, albeit rarely, human TB. In PNAS, Wu et al. (1) report the...

Clostridium perfringens enterotoxin (CPE) is a three-domain polypeptide, which binds to Claudin-3 and Claudin-4 with high affinity. Because these receptors are highly differentially expressed in many human tumors, claudin-3 and claudin-4 may provide an efficient molecular tool to specifically identify and target biologically aggressive human cancer cells for CPE-specific binding and cytolysis. In...

A rapid method for the determination of free formaldehyde in cod is described. It uses a simple water extraction of formaldehyde which is then derivatised with 2,4-dinitrophenylhydrazine (DNPH) to form a sensitive and specific chromophore for high-performance liquid chromatography (HPLC) detection. Although this formaldehyde derivative has been widely used in past tissue analysis, this paper...
