Synthesis of glycine betaine from exogenous choline in the moderately halophilic bacterium Halomonas elongata
(American Society for Microbiology, 1998)
The role of choline in osmoprotection in the moderate halophile Halomonas elongata has been examined. Transport and conversion of choline to betaine began immediately after addition of choline to the growth medium. ...

Effector specificity mutants of the transcriptional activator NahR of naphthalene degrading Pseudomonas define protein sites involved in binding of aromatic inducers
(American Society for Biochemistry and Molecular Biology Inc., 1997)
This work reports a genetic analysis of the interactions between NahR, the LysR-type regulator of the NAH operons for biodegradation of naphthalene in Pseudomonas, and its aromatic effectors. Six mutants encoding NahR ...

Identification of a gene encoding a thioredoxin-like product necessary for cytochrome c biosynthesis and symbiotic nitrogen fixation in Rhizobium leguminosarum
(American Society for Microbiology, 1994)
A Tn5-induced mutant of Rhizobium leguminosarum bv. viciae could not form nitrogen-fixing nodules on pea or vetch because of a lesion in electron transport to oxygen. The mutant lacked spectroscopically detectable cytochromes ...

Characterization of the cycHJKL genes involved in cytochrome c biogenesis and symbiotic nitrogen fixation in rhizobium leguminosarum
(American Society for Microbiology, 1995)
Mutants of Rhizobium leguminosarum bv. viciae unable to respire via the cytochrome aa3 pathway were identified by the inability to oxidize N,N*-dimethyl-p-phenylenediamine. Two mutants which were complemented by cosmid ...
