Internalization of a polysialic acid-binding Escherichia coli bacteriophage into eukaryotic neuroblastoma cells

Curli fibers mediate internalization of Escherichia coli by eukaryotic cells.

Curli fibers are adhesive surface fibers expressed by Escherichia coli and Salmonella enterica that bind several host extracellular matrix and contact phase proteins and were assumed to have a role in pathogenesis. The results presented here suggest that one such role is internalization into host cells. An E. coli K-12 strain transformed with a low-copy vector containing the gene cluster encodi...

Lysis of Escherichia coli cells induced by bacteriophage T4.

Structural changes in the envelope of Escherichia coli cells accompanying their lysis from without by bacteriophage T4 have been studied. The hypothesis concerning the role of collapse of membrane potential and formation of periplasmic vesicles in the process of lysis from without has been advanced.

Cloning of Binding Domain of Clostridium botlllinum Toxin Type A in Escherichia coli

Biosynthesis of the polysialic acid capsule in Escherichia coli K1. The endogenous acceptor of polysialic acid is a membrane protein of 20 kDa.

The nature of endogenous acceptor molecules implicated in the membrane-directed synthesis of the polysialic acid (polySia) capsule in Escherichia coli K1 serotypes is not known. The capsule contains at least 200 sialic acid (Sia) residues that are elongated by the addition of new Sia residues to the nonreducing termini of growing nascent chains (Rohr, T. E., and Troy, F. A. (1980) J. Biol. Chem...
