The structural genes (hupSL) of the membrane-bound NiFe-containing H2-uptake hydrogenase (Hup) of Azotobacter chroococcum were identified by oligonucleotide screening and sequenced. The small subunit gene (hupS) encodes a signal sequence of 34 amino

Characterization of two genes (hupD and hupE) required for hydrogenase activity in Azotobacter chroococcum

Autor: L, Du, F, Stejskal, K H, Tibelius

Publikováno v: FEMS microbiology letters. 75(1)

In Azotobacter chroococcum the hydrogenase structural genes (hupSL) cover about 2.8 kb of a 15-kb region associated with hydrogen-uptake (Hup) activity. Two other genes in this region, hupD and hupE, were located 8.9 kb downstream of hupL and were sh

Uptake hydrogenase activity in denitrifying Azospirillum brasilense grown anaerobically with nitrous oxide or nitrate

Autor: R Knowles, K H Tibelius

Publikováno v: Journal of Bacteriology. 157:84-88

zospirillum brasilense Sp7 was grown anaerobically with N2O as the terminal electron acceptor and NH4Cl as the nitrogen source. Hydrogen uptake activity (O2-dependent H3H oxidation) was expressed in the presence and absence of 5% H2; it reached its m

Hydrogenase activity in Azospirillum brasilense is inhibited by nitrite, nitric oxide, carbon monoxide, and acetylene

Autor: K H Tibelius, R Knowles

Publikováno v: Journal of Bacteriology. 160:103-106

Nitrite, NO, CO, and C2H2 inhibited O2-dependent H2 uptake (H3H oxidation) in denitrifying Azospirillum brasilense Sp7 grown anaerobically on N2O or NO3-. The apparent Ki values for inhibition of O2-dependent H2 uptake were 20 microM for NO2-, 0.4 mi
