Wild-type strains of Escherichia coli K-12 accumulate toxic concentrations of methylglyoxal when grown in medium containing adenosine 3',5'-monophosphate and either d-xylose, l-arabinose, or d-glucose-6-phosphate, independent of the presence of other carbon sources. Mutations at a locus called cxm specifically block methylglyoxal formation from xylose in(More)
The nifL gene product of Klebsiella pneumoniae inhibits the activity of the positive activator protein NifA in response to increased levels either of fixed nitrogen or of oxygen in the medium. In order to demonstrate that the responses to these two effectors are discrete we have subjected nifL to hydroxylamine mutagenesis and isolated nifL mutants that are(More)
Human hemoglobin was characterized as an enzyme in a reconstituted aniline hydroxylase system containing hemoglobin, NADPH, rat liver cytochrome P-450 reductase, aniline and atmospheric O2. This system catalyzed p-aminophenol formation (turnover number 0.2 mol/min/mol of hemoglobin) with an efficiency similar to that which has been reported for either(More)
