Pneumolysin

From Wikipedia, the free encyclopedia
3D structure of pneumolysin

Pneumolysin is avirulence factor of theGram-positive bacteriaStreptococcus pneumoniae.[1]

It is apore-forming toxin of 53 kDa composed of 471amino acids.[2] It has a range ofbiological activity, including the ability tolyse[3] and interfere with the function of cells and soluble molecules of the immune system.[4]

Released pneumolysin will aid the bacteria during colonization by facilitating adherence to the host,[5] during invasion by damaging host cells[6] and during infection by interfering with the host immune response.[7]

The presence of pneumolysin insputum,[8]urine,[9]CSF[10] andblood[11] can be indicative of anS. pneumoniae infection.
