Crystal structure of 4-chlorocatechol 1,2-dioxygenase from the chlorophenol-utilizing gram-positive Rhodococcus opacus 1CP.
The crystal structure of the 4-chlorocatechol 1,2-dioxygenase from the Gram-positive bacterium Rhodococcus opacus (erythropolis) 1CP, a Fe(III) ion-containing enzyme involved in the aerobic biodegradation of chloroaromatic compounds, has been solved by multiple wavelength anomalous dispersion using the weak anomalous signal of the two catalytic irons (1 Fe/257 amino acids) and refined at a 2.5 ...
متن کاملA sensitive colorimetric assay for identification of Acinetobacter baumannii using unmodified gold nanoparticles.
AIMS Acinetobacter baumannii is a global health problem, which threatens many healthcare settings. The current study aims to develop a detection assay for Ac. baumannii using unmodified gold nanoparticles (AuNPs). METHODS AND RESULTS Fifty-three Ac. baumannii clinical isolates were collected from Egyptian hospitals. Bacterial isolation and biochemical identification of isolates were carried o...
متن کاملCharacterization of the chromosomal cephalosporinases produced by Acinetobacter lwoffii and Acinetobacter baumannii clinical isolates.
The beta-lactamases produced by Acinetobacter lwoffii ULA-501, Acinetobacter baumannii ULA-187, and A. baumannii AC-14 strains were purified and characterized, and their kinetic interactions with several beta-lactam molecules, including substrates and inhibitors, were studied in detail. The three enzymes appeared to be cephalosporinases with different acylation efficiencies (kcat/Km ratio value...
متن کاملContribution of the A. baumannii A1S_0114 Gene to the Interaction with Eukaryotic Cells and Virulence
Genetic and functional studies showed that some components of the Acinetobacter baumannii ATCC 17978 A1S_0112-A1S_0119 gene cluster are critical for biofilm biogenesis and surface motility. Recently, our group has shown that the A1S_0114 gene was involved in biofilm formation, a process related with pathogenesis. Confirming our previous results, microscopy images revealed that the ATCC 17978 Δ0...
متن کاملA survey of indigenous microbial hydrocarbon degradation genes in soils from Antarctica and Brazil.
Total community DNA from 29 noncontaminated soils and soils impacted by petroleum hydrocarbons and chloro-organics from Antarctica and Brazil were screened for the presence of nine catabolic genes, encoding alkane monooxygenase or aromatic dioxygenases, from known bacterial biodegradation pathways. Specific primers and probes targeting alkane monooxygenase genes were derived from Pseudomonas pu...
