(Borisov and Verkhovsky, 2015). The polar residues (Arg 71, Asp 75, His 98 and Glu 101) of subunit I may form the ubiquinone binding site. Ile 102, Met 79, Phe 103 and a series of His ligands for the hemes may mediate electron transport from ubiquinol to hemeb, then to the ...
The purified Escherichia coli cytochrome bo3 ubiquinol oxidase contains four subunits that are each integral components of the cytoplasmic membrane. The molecular weight of each of the subunits has been determined by matrix-assisted laser desorption ionization mass spectrometry (MALDI). The observed molecu...
In addition, a catalase activity was reported for cytochrome bd-I from E. coli [61]. The small protein CydX is required for the function of the enzyme and has been proposed to be an additional subunit of the complex [28], [29]. Relevant to patho-physiology, cytochrome bd oxidase is ...
Cytochrome bd is a quinol peroxidase. We tested whether cytochrome bd could function as a peroxidase with its natural oxidase substrate, ubiquinol. Reduced decylubiquinone was used as replacement for the natural Scientific Reports | 6:27631 | DOI: 10.1038/srep27631 5 www.nature.com/scientific...
The results excluded the fully oxidized form of the enzyme from the rapid catalytic cycle of cytochrome bd oxidase. A re-investigation by both Flow-Flash and EPR on the previously reported mutant at Glu445 in subunit I, uncovered the dithionite-resistant ferric heme b595. Electrometrics data ...
Subunit CydX of Escherichia coli cytochrome bd ubiquinol oxidase is essential for assembly and stability of the di-heme active site. FEBS Lett. 2014;588:1537–41. 18. Chen H, Luo Q, Yin J, Gao T, Gao H. Evidence for the requirement of CydX in function but not assembly of the cyto...
