Two distinct azurins function in the electron-transport chain of the obligate methylotroph Methylomonas J.
Methylomonas J is an obligate methylotroph although it is unable to grow on methane. Like Pseudomonas AM1, it produces two blue copper proteins when growing on methylamine, one of which is the recipient of electrons from the methylamine dehydrogenase. When grown on methanol, only the other blue copper protein is produced. We have determined the amino acid sequences of these blue copper proteins...
متن کاملAn inducible periplasmic blue copper protein from Paracoccus denitrificans. Purification, properties, and physiological role.
When grown on methylamine as a sole carbon source, Paracoccus denitrificans synthesizes a Type I blue copper protein which mediates electron transfer between methylamine dehydrogenase and cytochrome c. This blue copper protein does not serve as an electron acceptor for methanol dehydrogenase and is not synthesized by cells grown on methanol or succinate. The blue copper protein and methylamine ...
متن کاملApplication of copper oxide nanoparticles modified glassy carbon electrode for electrocatalytic oxidation of methanol
Copper nanoparticles were fabricated by electro-reduction of CuSO4solution in the presence of cetyltrimethylammonium bromide (CTAB) cationic surfactant as an additive through potentiostatic method. The prepared copper nanoparticles were characterized by scanning electron microscopy (SEM) and electrochemical methods. The SEM images reveal that the nanoparticles with diameters at about 70 n...
متن کاملThe purification and properties of the soluble cytochromes c of the obligate methylotroph Methylophilus methylotrophus.
The obligate methylotroph Methylophilus methylotrophus contains three distinct soluble cytochromes c. The major cytochromes, cytochrome cH (about 50% of the total) and cytochrome cL (about 42%), were similar in most respects to the cytochromes cH and cL of the facultative methylotroph Pseudomonas AM1 [O'Keeffe & Anthony (1980) Biochem. J. 192, 411-419]. Cytochrome cH had a high isoelectric poin...
متن کاملThe Extractability of Inner-Membrane Proteins from Salmonella typhimurium Intact Cells, Spheroplasts and Inner-Membrane Fragments by Non-Denaturing Detergents
The effect of Triton X-100, Na cholate and Tween 80 on the solubilization of integral membrane proteins in intact cells, spheroplasts and inner-membrane fragments of Salmonella typhimurium was studied. The detergents were used in various concentrations (1.6 to 64 mM) and cytochromes b and d were used as marker to monitor the solubilization of membrane-bound proteins. Results showed that no inne...
