Transcriptional regulation of Nostoc hydrogenases: effects of oxygen, hydrogen, and nickel.
نویسندگان
چکیده
The transcription of structural genes encoding two hydrogenases in N(2)-fixing cultures of the cyanobacteria Nostoc muscorum and Nostoc sp. strain PCC 73102 were examined by reverse transcription-PCR. A low level of oxygen and addition of nickel induce higher transcript levels of both hydrogenases, whereas molecular hydrogen has a positive effect on the transcription of the genes encoding only the uptake hydrogenase.

Recombinant antibodies for specific detection of clostridial [Fe-Fe] hydrogenases
Biological hydrogen production is based on activity of specific enzymes called hydrogenases. Hydrogenases are oxygen sensitive metalloenzymes containing Ni and/or Fe atoms at the active site, catalyzing reversible reduction of protons. Generally, [Fe-Fe] hydrogenases prefer proton reduction to molecular hydrogen, a potential energy carrier molecule that can be produced by bioprocesses in sustai...
متن کاملComplex transcriptional control links NikABCDE-dependent nickel transport with hydrogenase expression in Escherichia coli.
Escherichia coli requires nickel under anaerobic growth conditions for the synthesis of catalytically active NiFe hydrogenases. Transcription of the NikABCDE nickel transporter, which is required for NiFe hydrogenase synthesis, was previously shown to be upregulated by FNR (fumarate-nit rate regulator) in the absence of oxygen and repressed by the NikR repressor in the presence of high extracel...
متن کاملThe role of nickel and iron-sulfur centers in the bioproduction of hydrogen
Hydrogenases are generally classified as iron-sulfur-containing proteins with four to twelve iron atoms in different cluster arrangements. Through physiological, chemical and spectroscopic studies,nickel has also been found to be a constitutive metal of several hydrogenases and shown to be involved in a redox linked process. The [NiFe] hydropnnses are now the most intensivelly studied nickel en...
متن کاملSynthesis, structure and reactivity of Ni site models of [NiFeSe] hydrogenases.
A series of structural models of the Ni centre in [NiFeSe] hydrogenases has been developed which exhibits key structural features of the Ni site in the H2 cycling enzyme. Specifically, two complexes with a hydrogenase-analogous four-coordinate 'NiS3Se' primary coordination sphere and complexes with a 'NiS2Se2' and a 'NiS4' core are reported. The reactivity of the complexes towards oxygen and pr...
متن کاملHydrogenases and hydrogen metabolism of cyanobacteria.
Cyanobacteria may possess several enzymes that are directly involved in dihydrogen metabolism: nitrogenase(s) catalyzing the production of hydrogen concomitantly with the reduction of dinitrogen to ammonia, an uptake hydrogenase (encoded by hupSL) catalyzing the consumption of hydrogen produced by the nitrogenase, and a bidirectional hydrogenase (encoded by hoxFUYH) which has the capacity to bo...
