The multidrug/oligosaccharidyl‐lipid/polysaccharide (MOP) exporter superfamily (TC# 2. A.
66) consists of four previously recognized families:(a) the ubiquitous multi‐drug and toxin …

BtuCD is an adenosine triphosphate–binding cassette (ABC) transporter that translocates
vitamin B12 from the periplasmic binding protein BtuF into the cytoplasm of Escherichia coli …

The genomes of eleven Gram-positive bacteria that are important for human health and the
food industry, nine low G+ C lactic acid bacteria and two high G+ C Gram-positive …

Extracytoplasmic solute binding receptors are constituents of primary and secondary active
transport systems. Previous studies have shown that the constituents of two such families …

BtuCD is an ATP binding cassette (ABC) transporter that facilitates uptake of vitamin B12
into the cytoplasm of Escherichia coli. The crystal structures of BtuCD and its cognate …

The bacterial phosphotransferase system (PTS) is a structurally and functionally complex
system with a surprising evolutionary history. The substrate-recognizing protein constituents …

BtuCD is an ABC transporter catalyzing the uptake of vitamin B12 across the Escherichia
coli inner membrane. A previously reported X-ray structure of BtuCD in complex with the …

Studies on membrane protein folding have focused on monomeric α-helical proteins and a
major challenge is to extend this work to larger oligomeric membrane proteins. Here, we …

We developed novel programs for displaying and analyzing the transmembrane α-helical
segments (TMSs) in the aligned sequences of homologous integral membrane proteins …

This is a reply to an article published in a previous issue of Microbiology (4). We first
demonstrated cohesion of replicated oriC copies in E. coli cells (temperature sensitive dnaA …
