Cytochrome c oxidase from Azotobacter vinelandii.
Although the terminal respiratory chain of Azotobacter has been the subject of several recent studies, the nature of the cytochrome oxidase portion is still somewhat obscure. Repaske (1) partially purified and characterized a soluble succinic dehydrogenase and succinoxidase system from Azotobacter z&elan&i. Wilson and Wilson (2) studied the soluble succinoxidase in Repaske’s preparation and dem...

15 صفحه اولPurification and properties of reduced diphosphopyridine nucleotide oxidase from Azotobacter.
Few studies on purified bacterial reduced diphosphopyridine nucleotide (DPNH) or cytochrome oxidases have been reported, although cytochrome reduction by DPNH’ in crude bacterial extracts has repeatedly been described (l-6). Dolin (7, 8) purified a flavoprotein DPNH oxidase and peroxidase from Streptococcus jaecalis, and Lenhoff and Kaplan (9) and Lenhoff et al. (10) described the characteristi...
متن کاملThe terminal oxidation system of Azotobacter vinelandii.
Preliminary work showed that Azotobacter vinelandii strain 0 (A2otobacter agile var. vinelandii) yielded a more stable enzyme extract than any other species tried, and this organism was used throughout. Repaske (1954) and Alexander and Wilson (1954) have reported the essential details for growing and harvesting the culture and for making the enzyme preparations. The succinic dehydrogenase (SD) ...
متن کاملTetramethyl-p-phenylenediamine oxidase reaction in Azotobacter vinelandii.
It was possible to quantitate the tetramethyl-p-phenylenediamine (TMPD) oxidase reaction in Azotobacter vinelandii strain O using turbidimetrically standarized resting cell suspensions. The Q(O2) value obtained for whole cell oxidation of ascorbate-TMPD appeared to reflect the full measure of the high respiratory oxidative capability usually exhibited by this genera of organisms. The Q(O2) valu...
