Infrared studies on the interaction of carbon monoxide with divalent nickel in hydrogenase from Chromatium vinosum.
Infrared spectra of a carbon monoxy-bound form of the EPR silent Ni(II) species of hydrogenase isolated from Chromatium vinosum are presented. These spectra show a band at 2060 cm-1 due to v(CO) for a metal-CO complex. This absorbance shifts to 2017 cm-1 upon exposure of the enzyme to 13CO. This band is attributed to v(CO) from a Ni(II)-CO species. It is shown that the CO on this species is pho...
متن کاملSurface structure of Chromatium okenii and Chromatium weissei.
The outermost structured layer of both Chromatium weissei and C. okenii is composed of a hexagonal array of hollow cone-shaped subunits approximately 25 nm in length and 13 nm in diameter.
متن کاملCarbon metabolism in Chromatium.
The purple photosynthetic sulfur bacterium, Chromatium, will grow only in the light and under anaerobic conditions. This organism can grow on an inorganic medium utilizing CO2 as the sole carbon source in the presence of reduced inorganic sulfur compounds. Some reduced carbon compounds can be utilized for the growth of this organism but only in the light and under anaerobic conditions. In this ...
متن کاملPyridine nucleotide transhydrogenase from Chromatium.
The isolation and purification of a soluble transhydrogenase from Chromatium is described. The enzyme promotes the oxidation of reduced triphosphopyridine nucleotide by diphosphopyridine nucleotide. However, it will also use several analogues of DPN and TPN which include deamino-DPN, deamino-TPN, thionicotinamide DPN, and deamino-DPNH. Nicotinamide mononucleotide was also reduced. The enzyme do...
متن کاملHigh degree of similarity between Chromatium vinosum and Chromatium minutissimum as revealed by riboprinting.
The riboprinting technique (restriction fragment length polymorphism [RFLP] analysis of PCR-amplified ribosomal DNA) was used to study five strains representing three species of the genus Chromatium. An RFLP analysis following digestion of the amplified small-subunit ribosomal DNA with 25 restriction enzymes revealed that the patterns obtained for all strains of Chromatium vinosum were identica...
