An active tryptic fragment of hydrogenase 2 from Escherichia coli has been isolated from the periplasmic face of the cytoplasmic membrane, and the large and small subunits N-terminally sequenced. The(More)
The Escherichia coli mob locus is required for synthesis of active molybdenum cofactor, molybdopterin guanine dinucleotide. The mobB gene is not essential for molybdenum cofactor biosynthesis because(More)
Molybdenum-dependent repression of transcription of the Escherichia coli modABCD operon, which encodes the high-affinity molybdate transporter, is mediated by the ModE protein. This regulatory(More)
The molybdate-dependent transcriptional regulator ModE of Escherichia coli functions as a sensor of intracellular molybdate concentration and a regulator for the transcription of several operons that(More)
