Pseudomonas aeruginosa exoenzyme S is an adhesion.
Exoenzyme S from Pseudomonas aeruginosa has been studied as an adhesion for glycosphingolipids and buccal cells. Binding of exoenzyme S to gangliotriosylceramide (GalNAc beta 1-4Gal beta 1-4Glc beta 1-1Cer), gangliotetraosylceramide (Gal beta 1-3 GalNAcT beta 1-4 Gal beta 1-4Glc beta 1-1Cer), and lactosylceramide (Gal beta 1-4Glc beta 1-1Cer) separated on thin-layer chromatograms was observed. ...
متن کاملPurification of Pseudomonas aeruginosa exoenzyme S.
Pseudomonas aeruginosa produces two distinct ADP-ribosyl transferases, exotoxin A and exoenzyme S, which differ in a number of properties including substrate specificity. Exoenzyme S was purified from culture supernatants of P. aeruginosa DG1. The procedure for purification consists of four major steps: ammonium sulfate precipitation, anion-exchange chromatography on DEAE-Sephacel, acetone prec...
متن کاملPseudomonas aeruginosa exoenzyme S is a biglutamic acid ADP-ribosyltransferase.
Kinetic analysis of two mutations within Pseudomonas aeruginosa exoenzyme S (ExoS) showed that a E379D mutation inhibited expression of ADP-ribosyltransferase activity but had little effect on the expression of NAD glycohydrolase activity while a E381D mutation inhibited expression of both activities. These data identify ExoS as a biglutamic acid ADP-ribosyltransferase, where E381 is the cataly...
متن کاملPseudomonas aeruginosa exoenzyme S stimulates murine lymphocyte proliferation in vitro.
The exuberant immunoinflammatory response that is associated with Pseudomonas aeruginosa infection is the major source of the morbidity and mortality in cystic fibrosis (CF) patients. Previous studies have established that an exoproduct of P. aeruginosa (exoenzyme S) is a mitogen for human T lymphocytes and activates a larger percentage of T cells than most superantigens, which may contribute t...
متن کاملPurification and characterization of exoenzyme S from Pseudomonas aeruginosa 388.
Exoenzyme S was purified > 1,500-fold from the culture supernatant fluid of Pseudomonas aeruginosa 388 at high yield without utilization of solvents or detergents. Two proteins, with apparent molecular sizes of 53 and 49 kDa, cofractionated with exoenzyme S activity. Rabbit anti-49-kDa-protein immunoglobulin G was prepared by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis-purif...
