Peptide utilization in Pseudomonas aeruginosa: evidence for membrane-associated peptidase

Pseudomonas aeruginosa outer membrane: peptidoglycan-associated proteins.

The Pseudomonas aeruginosa outer membrane was isolated with attached peptidoglycan and fractionated with Triton X-100, ethylenediaminetetraacetate, and lysozyme. The data suggest that major outer membrane proteins F, H2, and I are noncovalently associated with the peptidoglycan.

Utilization of carbohydrates by Pseudomonas aeruginosa.

Evidence for the location of OprM in the Pseudomonas aeruginosa outer membrane.

OprM with a M(r) of 49 K is associated with the multidrug resistance of Pseudomonas aeruginosa. Detergent fractionation of bacterial cells has demonstrated that OprM is located in the outer membrane from which it sediments with the other major outer membrane proteins. In this study we have determined the location of OprM as the P. aeruginosa outer membrane. Western immunoblots of cell fractions...

A new mechanism for membrane iron transport in Pseudomonas aeruginosa.

Various biochemical and biophysical studies have demonstrated the existence of a novel iron-uptake mechanism in Pseudomonas aeruginosa, different from that generally described for ferrichrome and ferric-enterobactin in Escherichia coli. This new iron-uptake mechanism involves all the proteins generally reported to be involved in the uptake of ferric-siderophore complexes in Gram-negative bacter...

Antibiotic utilization and Pseudomonas aeruginosa resistance in intensive care units.

Pseudomonas aeruginosa is one of the most frequent and dangerous pathogens involved in the etiology of severe nosocomial infections. A retrospective observational study was conducted at all intensive care units of the University Hospital in Olomouc, Czech Republic (155 ICU beds). Complete antibiotic utilization data of the ICUs in the period of 1999 to 2008 were processed according to ATC/DDD s...
