porins การใช้

• Cooperation with pili for CR3-mediated internalization is another function of porins.
• Strains of the same species can express different porins.
• General diffusion porins usually assemble as a beta strands.
• Porins are also an important factor for complement inhibition for both pathogenic and commensal species.
• Porins are important for nutrient acquisition.
• It has been shown that a number of porins are evolutionarily related, and these porins are:
• It has been shown that a number of porins are evolutionarily related, and these porins are:
• Beta-lactam and fluoroquinolone antibiotics must pass through porins to reach their targets in gram negative bacteria.
• Porins are chemically selective  transporting only one group of molecules  or may be specific for one molecule.
• Unlike the outer membrane, the inner membrane doesn't contain porins, and is highly impermeable to all molecules.
• Ability to translocate into host cells and modulate reactive oxygen species production and apoptosis is made possible by porins, as well.
• As porins are the major outer membrane proteins, they also serve as receptor sites for the binding of phages and bacteriocins.
• OmpG forms a 14-stranded beta-barrel and in contrast to most porins, appears to function as a monomer.
• There is no reason to have an article about porins AND lipopolysaccharides . talk ) 13 : 07, 6 November 2010 ( UTC)
• However, channels called porins are present in the outer membrane that allow for passive transport of many ions, sugars and amino acids across the outer membrane.
• Porins are also recognized by TLR2, they bind complement factors ( C3b, C4b, factor H, and C4bp ( complement factor 4b-binding protein ) ).
• Fluoroquinolones can enter cells easily via porins and, therefore, are often used to treat intracellular pathogens such as " Legionella pneumophila " and " Mycoplasma pneumoniae ".
• In gram-negative bacteria, the inner membrane is the major permeability barrier, whereas the outer membrane contains porins, which render it largely permeable to molecules less than about 1500 daltons.
• The cell wall of " N . gonorrhoeae " contains porins which are holes within the cell wall in which some molecules are able to diffuse into or out of the cell membrane.
