The mechanism of lipopolysaccharide (LPS) transport in Gram-negative bacteria from the inner membrane to the outer membrane is largely unknown. Here, we investigated the possibility that LPS transport proceeds via a soluble intermediate associated with a periplasmic chaperone analogous to the Lol-dependent transport mechanism of lipoproteins. Whereas newly(More)
Attacin is a 20 kDa antibacterial protein, originally isolated from the immune haemolymph of Hyalophora cecropia. It has been demonstrated previously that attacin causes increased permeability of the outer membrane of Escherichia coli and inhibition of outer-membrane protein synthesis at the transcriptional level. This is accompanied by inhibition of(More)
The outer membrane of Gram-negative bacteria contains phospholipids and lipopolysaccharide (LPS) in the inner and outer leaflet, respectively. Little is known about the transport of the phospholipids from their site of synthesis to the outer membrane. The inner membrane protein MsbA of Escherichia coli, which is involved in the transport of LPS across the(More)
The SecA and SecB proteins are involved in protein translocation in Escherichia coli. Immunoblot analysis was used to investigate the possible conservation of these proteins in prokaryotes. Cross-reacting proteins were detected in all other Enterobacteriaceae tested, but not in microorganisms more distantly related from Escherichia coli.
Malassezia pachydermatis is a basidiomycetous yeast that causes infections in humans and animals. Here, we report the genome sequence of Malassezia pachydermatis strain CBS 1879, which will facilitate the study of mechanisms underlying pathogenicity of the only non-lipid-dependent Malasezzia species.
BACKGROUND Aspergillus tubingensis is a black Aspergillus belonging to the Aspergillus section Nigri, which includes species that morphologically resemble Aspergillus niger. Recent developments in species determination have resulted in clinical isolates presumed to be Aspergillus niger being reclassified as Aspergillus tubingensis by sequencing. We present(More)
Representatives of the genus Aspergillus are opportunistic fungal pathogens. Their conidia can reach the alveoli by inhalation and can give rise to infections in immunocompromised individuals. Aspergillus fumigatus is the causal agent of invasive aspergillosis in nearly 90% of the cases. It is not yet well-established what makes this fungus more pathogenic(More)
