The cell surface expression of group 2 capsular polysaccharides in Escherichia coli: the role of KpsD, RhsA and a multi‐protein complex at the pole of the cell
The export of large negatively charged capsular polysaccharides across the outer membrane represents a significant challenge to Gram negative bacteria. In the case of Escherichia coli group 2Expand

pH-induced Collapse of the Extracellular Loops ClosesEscherichia coli Maltoporin and Allows the Study of Asymmetric Sugar Binding*
LamB (maltoporin) is essential for the uptake of maltose and malto-oligosaccharides across the outer membrane ofEscherichia coli. Purified LamB was reconstituted in artificial lipid bilayer membranesExpand

Porin OmpP2 of Haemophilus influenzae Shows Specificity for Nicotinamide-derived Nucleotide Substrates*
Haemophilus influenzae has an absolute requirement for NAD (factor V) because it lacks all biosynthetic enzymes necessary for de novo synthesis of that cofactor. Therefore, growth in vitro requiresExpand

Emotion and community in a semeiotic perspective
Abstract The article investigates emotions from a semeiotic perspective. The American philosopher Charles S. Peirce (1839–1914) defined the emotion as a legisign, which is a lawsign (cf. Savan 1981).Expand

Negotiating the meaning of artefacts: Branding in a semeiotic perspective
Abstract The article investigates the question of how we ascribe meaning to artefacts (understood in its broadest sense, also including brands). The short answer is that meaning is ascribed to brandsExpand

CymA of Klebsiella oxytoca outer membrane: binding of cyclodextrins and study of the current noise of the open channel.
CymA, the outer membrane component of the cyclodextrin (CD) uptake and metabolism system of Klebsiella oxytoca, was reconstituted into lipid bilayer membranes. The channel properties of this unusualExpand

Site-directed mutagenesis of tyrosine 118 within the central constriction site of the LamB (Maltoporin) channel of Escherichia coli. I. Effect on ion transport.
The three-dimensional structure of the malto-oligosaccharide-specific LamB-channel of Escherichia coli (also called maltoporin) is known from x-ray crystallography. The central constriction of theExpand

Site-directed mutagenesis of tyrosine 118 within the central constriction site of the LamB (maltoporin) channel of Escherichia coli. II. Effect on maltose and maltooligosaccharide binding kinetics.
The 3-D structure of the maltooligosaccharide-specific LamB channel of Escherichia coli (also called maltoporin) is known from x-ray crystallography. The central constriction of the channel formed byExpand
