Motility and protein secretion are key processes contributing to bacterial virulence. A wealth
of phylogenetic, biochemical and structural evidence support the hypothesis that the widely …

In contrast to other organisms, gram-negative bacteria have evolved numerous systems for
protein export. Eight types are known that mediate export across or insertion into the …

The type II secretion (T2S) system is responsible for extracellular secretion of a broad range
of proteins, including toxins and degradative enzymes that play important roles in the …

The type two secretion system (T2S) is important for virulence of a number of gram-negative
bacterial plant pathogens. Most of the T2S-secreted proteins that have been characterized to …

MtrC and OmcA are cell surface-exposed lipoproteins important for reducing solid metal
oxides. Deletions of type II secretion system (T2SS) genes reduced their extracellular …

Gram-negative bacteria translocate various proteins including virulence factors across their
outer membrane via type 2 secretion systems (T2SSs). T2SSs are thought to contain a …

The natural alkaloids of tryptanthrin and their derivatives have a wide range of biological
activities. In this research, four series of azatryptanthrin derivatives containing 4-aza/3-aza/2 …

Background Pseudomonas fluorescens F113 is a plant growth-promoting rhizobacterium
(PGPR) isolated from the sugar-beet rhizosphere. This bacterium has been extensively …

The soft rot Erwinia are members of the most studied bacterial family, the
Enterobacteriaceae, which also includes other important plant and animal pathogens such …

Type II secretion systems (T2SSs) are critical for secretion of many proteins from Gram-
negative bacteria. In the T2SS, the outer membrane secretin GspD forms a multimeric pore …
