Isolation of carbohydrate-reactive outer membrane proteins of Aeromonas hydrophila.
Outer membrane proteins of Aeromonas hydrophila A6 were isolated by affinity chromatography on the basis of their reactivity with trisaccharide structures analogous to the terminal trisaccharide of the H antigen of the human ABO(H) blood group system and were characterized by using antisera raised against the isolate. The outer membrane extract for affinity chromatography was prepared from pres...
متن کاملOuter-membrane pore-forming proteins in gram-negative anaerobic bacteria.
The outer-membrane proteins (OMPs) of bacteria function as the dynamic interface between the bacterium and its surroundings and are involved in maintenance of cell structure, binding a variety of substances, adhesion to other cells, and regulation of transport of both nutrients and bactericidal agents. There is a vast amount of information about aerobic OMPs and their roles in immunogenicity, v...
متن کاملProperties and Phylogeny of 76 Families of Bacterial and Eukaryotic Organellar Outer Membrane Pore-Forming Proteins
We here report statistical analyses of 76 families of integral outer membrane pore-forming proteins (OMPPs) found in bacteria and eukaryotic organelles. 47 of these families fall into one superfamily (SFI) which segregate into fifteen phylogenetic clusters. Families with members of the same protein size, topology and substrate specificities often cluster together. Virtually all OMPP families in...
متن کاملTopographic labelling of pore-forming proteins from the outer membrane of Escherichia coli.
The topography of three pore-forming proteins from the outer membrane of Escherichia coli has been explored by using two labelling techniques. Firstly, the distribution of nucleophilic residues has been investigated by selective chemical modification using arylglyoxals (for arginine residues), isothiocyanates (for lysine residues), carbodi-imides (for carboxy residues) and diazonium salts. Seco...
متن کاملPore-forming ability of major outer membrane proteins from Wolinella recta ATCC 33238.
Three major outer membrane proteins with apparent molecular masses of 43, 45, and 51 kDa were purified from Wolinella recta ATCC 33238, and their pore-forming abilities were determined by the black lipid bilayer method. The non-heat-modifiable 45-kDa protein (Omp 45) showed no pore-forming activity even at high KCl concentrations. The single-channel conductances in 1 M KCl of the heat-modifiabl...
