A Clinical and Genetic Study of Psoriatic Arthritis Psoriatic arthritis (PsA) is an inflammatory joint disease associated with psoriasis. PsA has a heterogeneous pattern, expressed by different manifestations such as mild mono-oligoarthritis or very severe, erosive and destructive polyarthritis. Measurable inflammatory activity is not always prominent. The aetiology is unknown but genetic facto...

TldD and TldE proteins are involved in the biosynthesis of microcin B17 (MccB17), an Escherichia coli thiazole/oxazole-modified peptide toxin targeting DNA gyrase. Using a combination of biochemical and crystallographic methods we show that E. coli TldD and TldE interact to form a heterodimeric metalloprotease. TldD/E cleaves the N-terminal leader sequence from the modified MccB17 precursor pep...

Microcin B17 (MccB17) is a post-translationally modified peptide containing thiazole and oxazole heterocycles that interrupt the peptide backbone. MccB17 is capable of poisoning DNA gyrase through stabilization of the gyrase-DNA cleavage complex and has therefore attracted significant attention. Using a combination of Fmoc-strategy solid-phase peptide synthesis and solution-phase fragment assem...
