The membrane-bound hydrogenase from Paracoccus denitrificans. Purification and molecular characterization.

Abstract

The membrane-bound hydrogenase from Paracoccus denitrificans was purified 68-fold with a yield of 14.6%. The final preparation had a specific activity of 161.9 mumol H2 min-1 (mg protein)-1 (methylene blue reduction). Purification involved solubilization by Triton X-114, phase separation, chromatography on DEAE-Sephacel, ammonium-sulfate precipitation and… (More)
