Protein Secretion Systems in Gram-Negative Bacteria
P rotein export systems are present in all living organisms, including gram-negative bacteria and the eukaryotic organelles that derived from them (Table 1). In contrast to other organisms, however, gram-negative bacteria contain numerous, apparently independent systems for exporting proteins, including at least eight types that mediate export across or insertion into the inner cytoplasmic memb...
متن کاملthe type i and ii secretory systems in gram-negative bacteria
bacterial utilize a multitude of methods to secretion of specific substrate across phospholipid membranes. these bacterial strategies can play many roles in promoting bacterial process, from enhancing pathogenesis to bacterial response to environmental condition. the secretion in bacterial species transfer and release performance substance such as proteins, enzymes and metabolites to environmen...
متن کاملDeterminants of extracellular protein secretion in gram-negative bacteria.
Protein localization has been the subject of extensive research using models ranging from bacteria to mammalian cells. The central question which prokaryoticand eukaryotic-cell biologists have attempted to answer is how proteins synthesized in the cytoplasmic compartment traverse the hydrophobic membrane barrier or become integrated into it. This work has led to the identification of targeting ...
متن کاملCorrection: Prediction of Type III Secretion Signals in Genomes of Gram-Negative Bacteria
BACKGROUND Pathogenic bacteria infecting both animals as well as plants use various mechanisms to transport virulence factors across their cell membranes and channel these proteins into the infected host cell. The type III secretion system represents such a mechanism. Proteins transported via this pathway ("effector proteins") have to be distinguished from all other proteins that are not export...
متن کاملAn inner membrane platform in the type II secretion machinery of Gram-negative bacteria.
The type II secretion machinery allows most Gram-negative bacteria to deliver virulence factors into their surroundings. We report that in Erwinia chrysanthemi, GspE (the putative NTPase), GspF, GspL and GspM constitute a complex in the inner membrane that is presumably used as a platform for assembling other parts of the secretion machinery. The GspE-GspF-GspL-GspM complex was demonstrated by ...
