Azotobacter vinelandii mutS: nucleotide sequence and mutant analysis.
نویسندگان
چکیده
An Azotobacter vinelandii homolog to the Salmonella typhimurium mutS gene was discovered upstream of the fdxA gene. The product of this gene is much more similar to S. typhimurium MutS than either is to the HexA protein of Streptococcus pneumoniae. An A. vinelandii delta mutS mutant strain was shown to have a spontaneous mutation frequency 65-fold greater than that of the wild type.

Inactivation of the ampDE operon increases transcription of algD and affects morphology and encystment of Azotobacter vinelandii.
Transcription of algD, encoding GDP-mannose dehydrogenase, the key enzyme in the alginate biosynthetic pathway, is highly regulated in Azotobacter vinelandii. We describe here the characterization of a Tn5 insertion mutant (AC28) which shows a higher level of expression of an algD::lacZ fusion. AC28 cells were morphologically abnormal and unable to encyst. The cloning and nucleotide sequencing ...
متن کاملComplete Genome Sequences of Azotobacter vinelandii Wild-Type Strain CA and Tungsten-Tolerant Mutant Strain CA6
We report the complete genome sequences of Azotobacter vinelandii mutant strain CA6 and its parent wild-type strain, CA. When fixing nitrogen, strain CA6 displays slow growth and impaired molybdate uptake, tolerance to tungstates, and production of hydrogen gas, compared to results for strain CA. Comparing these genome sequences may provide a genetic basis for these mutant phenotypes.
متن کاملGenes in Azotobacter vinelandii
Azotobacter vinelandii contains a heterodimeric, membrane-bound [NiFelhydrogenase capable of catalyzing the reversible oxidation of H2. The 13 and at subunits of the enzyme are encoded by the structural genes hoxK and hoxG, respectively, which appear to form part of an operon that contains at least one further potential gene (open reading frame 3 1ORF3]). In this study, determination of the nuc...
متن کاملThe GacS sensor kinase regulates alginate and poly-beta-hydroxybutyrate production in Azotobacter vinelandii.
Azotobacter vinelandii produces two polymers: the extracellular polysaccharide alginate and the intracellular polyester poly-beta-hydroxybutyrate (PHB). A cosmid clone (pSMU588) from an A. vinelandii gene library diminished alginate production by A. vinelandii mucoid strain ATCC 9046. The nucleotide sequence and predicted amino acid sequence of the locus responsible for the mucoidy suppression ...
متن کاملGenetic analysis of Azotobacter vinelandii mutant strains unable to fix nitrogen.
Transformation was used to perform ratio test crosses with mutant strains of Azotobacter vinelandii unable to fix N2. Mutations that simultaneously eliminated both components of nitrogenase (nif-1 and nif-2) were tightly linked. The nif-45 mutation that resulted in the absence of an active molybdenum cofactor was closer to nif-1 and nif-2 than to any of the other nif mutations. Strains that lac...
