4 * 54000, recombinant alpha-subunnit, + 4 * 43000, recombinant beta-subunit, SDS-PAGE, (alphabeta)4 , the recombinant alpha subunit forms a dimeric structure and behaves as an NADH dehydrogenase, while the beta subunit is a tetramer that has sarcosine oxidase and L-proline dehydrogenase activity.. The SOX complex assembles into the heterooctameric (alphabeta)4 form and shows NADH dehydrogenase activity, transmission electron microscopy and gel filtration Thermococcus kodakarensis

additional information the alpha subunit shows sarcosine oxidase and L-proline dehydrogenase activity, while the beta subunit displays both sarcosine oxidase and L-proline dehydrogenase activity, but not NADH dehydrogenase activity, measurement of L-proline dehydrogenase activity with 2,6-dichloroindophenol as cofactor. Dye-linked NADH dehydrogenase activity is assayed with NADH, FAD and 2,6-dichloroindophenol Thermococcus kodakarensis ?

General Information

General Information Comment Organism
additional information the recombinant alpha subunit forms a dimeric structure and behaves as an NADH dehydrogenase, while the beta subunit is a tetramer that has sarcosine oxidase and L-proline dehydrogenase activity.. The SOX complex assembles into the hetero-octameric (alphabeta)4 form and shows NADH dehydrogenase activity, structure of isolated subunit tetramers, overview Thermococcus kodakarensis
physiological function sarcosine oxidase catalyzes the oxidation of the methyl group in sarcosine and transfer of the oxidized methyl group into the one-carbon metabolic pool, yielding equimolar glycine, hydrogen peroxide, and formaldehyde or 5,10-methylenetetrahydrofolate Thermococcus kodakarensis
