ATPase activity of the GyrB subunit was followed by measuring the release of  32P-labeled phosphate from reactions containing [y-32P]-ATP in the presence of GyrA and DNA (Figure 1).  Omission of DNA or GyrA (which binds DNA) resulted in dramatically reduced ATPase activity of GyrB.

Nucleoids from <i>E. coli</i> cells containing DNA labeled with [methyl-3H]thymidine were isolated and separated using an ethidium bromide-containing sucrose density gradient.  The sedimentation profiles were reported for gyrA and gyrB temperature-sensitive mutants at the permissive and non-permissive temperatures (Figure 1 & 2).  The ethidium bromide concentration is proportional to superhelical density, meaning that less supercoiled DNA from a gyrase mutant grown at the non-permissive temperature requires a lower concentration of ethidium bromide.

Purified E. coli gyrase was shown to induce cleavage and supercoiling in ColE1 DNA in the presence of ATP, but not after the addition of novobiocin or coumermycin A1 (Figure 2). Supercoiling of DNA was monitored by agarose gel electrophoresis (Figure 2A), while the hydrolysis of ATP was measured by following the release of 32-Pi measured by thin layer chromatography (Figure 2B).

The authors used 3 conditions (treatment with either a quinolone or coumarin anitbiotic or growth of a gyrAts mutant at non-permissive temperature) to alter negative supercoiling of DNA and measured the changes in gene expression by microarray analysis. More than 300 SSGs (supercoiling sensitive genes) were identified that responded rapidly to the experimental conditions.

ATPase activity of the GyrB subunit was followed by measuring the release of  32P-labeled phosphate from reactions containing [y-32P]-ATP in the presence of GyrA and DNA (Figure 1). Omission of DNA or GyrA (which binds DNA) resulted in dramatically reduced ATPase activity of GyrB.

Nucleoids from <i>E. coli</i> cells containing DNA labeled with [methyl-3H]thymidine were isolated and separated using an ethidium bromide-containing sucrose density gradient. The sedimentation profiles were reported for gyrA and gyrB temperature-sensitive mutants at the permissive and non-permissive temperatures (Figure 1 & 2).  The ethidium bromide concentration is proportional to superhelical density, meaning that less supercoiled DNA from a gyrase mutant grown at the non-permissive temperature requires a lower concentration of ethidium bromide.

Purified E. coli gyrase was shown to induce cleavage and supercoiling in ColE1 DNA in the presence of ATP, but not after the addition of novobiocin or coumermycin A1 (Figure 2). Supercoiling of DNA was monitored by agarose gel electrophoresis (Figure 2A), while the hydrolysis of ATP was measured by following the release of 32-Pi measured by thin layer chromatography (Figure 2B).

The authors used 3 conditions (treatment with either a quinolone or coumarin anitbiotic or growth of a gyrAts mutant at non-permissive temperature) to alter negative supercoiling of DNA and measured the changes in gene expression by microarray analysis. More than 300 SSGs (supercoiling sensitive genes) were identified that responded rapidly to the experimental conditions.

DNA-dependent ATPase activity

PMID:6094559[5]

F

ATPase activity of the GyrB subunit was followed by measuring the release of 32P-labeled phosphate from reactions containing [y-32P]-ATP in the presence of GyrA and DNA (Figure 1). Omission of DNA or GyrA (which binds DNA) resulted in dramatically reduced ATPase activity of GyrB.

DNA topological change

PMID:6327603[8]

IMP: Inferred from Mutant Phenotype

P

Nucleoids from E. coli cells containing DNA labeled with [methyl-3H]thymidine were isolated and separated using an ethidium bromide-containing sucrose density gradient. The sedimentation profiles were reported for gyrA and gyrB temperature-sensitive mutants at the permissive and non-permissive temperatures (Figure 1 & 2). The ethidium bromide concentration is proportional to superhelical density, meaning that less supercoiled DNA from a gyrase mutant grown at the non-permissive temperature requires a lower concentration of ethidium bromide.

F

Purified E. coli gyrase was shown to induce cleavage and supercoiling in ColE1 DNA in the presence of ATP, but not after the addition of novobiocin or coumermycin A1 (Figure 2). Supercoiling of DNA was monitored by agarose gel electrophoresis (Figure 2A), while the hydrolysis of ATP was measured by following the release of 32-Pi measured by thin layer chromatography (Figure 2B).

P

The authors used 3 conditions (treatment with either a quinolone or coumarin anitbiotic or growth of a gyrAts mutant at non-permissive temperature) to alter negative supercoiling of DNA and measured the changes in gene expression by microarray analysis. More than 300 SSGs (supercoiling sensitive genes) were identified that responded rapidly to the experimental conditions.
