The bacteriocinogenic plasmid pIP404 from Clostridium perfringens was isolated and cloned in Escherichia coli, and its physical map was deduced. Expression of the bcn gene, encoding bacteriocin BCN5, is inducible by UV irradiation of C. perfringens and thu ...
BACKGROUND: Gene transfer to nociceptive neurons of the dorsal root ganglia (DRG) is a promising approach to dissect mechanisms of pain in rodents and is a potential therapeutic strategy for the treatment of persistent pain disorders such as neuropathic pa ...
The specialized type III secretion (T3S) apparatus of pathogenic and symbiotic Gram-negative bacteria comprises a complex transmembrane organelle and an ATPase homologous to the F-1-ATPase beta subunit. The T3S ATPase HrcN of Pseudomonas syringae associate ...
An extensive random mutagenesis study on the function of nine residues in the subunit binding site of FimC was conducted to evaluate the mol. mechanisms of subunit binding by FimC and the contribution of chaperone surface residues. Five plasmid libraries o ...

Bacteria of the genus Vibrio are common members of aquatic environments where they compete with other prokaryotes and defend themselves against grazing predators. A macromolecular protein complex called the type VI secretion system (T6SS) is used for both ...
VIP, glucagon or several other neuropeptides were applied to intact retinae in vitro. VIP was found to be a very potent stimulator of cyclic AMP production in rabbit retina, whereas glucagon was efficient in pigeon retina. Attempts to modify the VIP-induce ...
