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 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 کاملTransferrin-iron uptake by Gram-negative bacteria.
Members of the families Neisseriaceae, Pasteurellaceae and Moraxellaceae are capable of transferrin-iron acquisition in the absence of siderophore production. They do so via expression of a bi-partite receptor composed of two dissimilar proteins, TbpA and TbpB. Both proteins are surface exposed, iron-regulated and capable of binding transferrin. However, other physiochemical, antigenic, and imm...
متن کاملLysis of gram-negative bacteria by serum.
The antibacterial property of serum, first reported by Nuttall in 1888, has attracted many investigators and an extensive literature has accumulated. The sera of most mammals tested have been found to possess bactericidal activity, but a notable exception is the mouse, whose serum, apparently through lack of complement, is unable to kill any of a number of bacterial strains which are sensitive ...
متن کاملSuper-Resolution Imaging of Protein Secretion Systems and the Cell Surface of Gram-Negative Bacteria
Gram-negative bacteria have a highly evolved cell wall with two membranes composed of complex arrays of integral and peripheral proteins, as well as phospholipids and glycolipids. In order to sense changes in, respond to, and exploit their environmental niches, bacteria rely on structures assembled into or onto the outer membrane. Protein secretion across the cell wall is a key process in virul...
