Quinoprotein alcohol dehydrogenase from ethanol-grown Pseudomonas aeruginosa.
Cell-free extracts of Pseudomonas aeruginosa strains, grown on ethanol, showed dye-linked alcohol dehydrogenase activities. The enzyme responsible for this activity was purified to homogeneity. It appeared to contain two molecules of pyrroloquinoline quinone per enzyme molecule. In many respects, it resembled other quinoprotein alcohol dehydrogenases (EC 1.1.99.8), having a substrate specificit...
متن کاملThe absence of quinoprotein alcohol dehydrogenase in Acinetobacter calcoaceticus.
It is shown that the unusual NAD(P)+-independent quinoprotein alcohol dehydrogenase, said previously to be responsible for oxidation of ethanol during growth of Acinetobacter calcoaceticus LMD 79.39, was in fact isolated from an unidentified organism which contained cytochrome c and which has now been lost. Several genuine strains of A. calcoaceticus do not contain cytochrome c nor do they cont...
متن کاملThermostable NAD-linked secondary alcohol dehydrogenase from propane-grown Pseudomonas fluorescens NRRL B-1244.
NAD-linked alcohol dehydrogenase activity was detected in cell-free crude extracts from various propane-grown bacteria. Two NAD-linked alcohol dehydrogenases, one which preferred primary alcohols (alcohol dehydrogenase I) and another which preferred secondary alcohols (alcohol dehydrogenase II), were found in propane-grown Pseudomonas fluorescens NRRL B-1244 and were separated from each other b...
متن کاملThe structure of the quinoprotein alcohol dehydrogenase of Acetobacter aceti modelled on that of methanol dehydrogenase from Methylobacterium extorquens.
The 1.94 A structure of methanol dehydrogenase has been used to provide a model structure for part of a membrane quinohaemoprotein alcohol dehydrogenase. The basic superbarrel structure and the active-site region are retained, indicating essentially similar mechanisms of action, but there are considerable differences in the external loops, particularly those involved in formation of the shallow...
متن کاملAlcohol dehydrogenase from Methylobacterium organophilum.
The alcohol dehydrogenase from Methylobacterium organophilum, a facultative methane-oxidizing bacterium, has been purified to homogeneity as indicated by sodium dodecyl sulfate-gel electrophoresis. It has several properties in common with the alcohol dehydrogenases from other methylotrophic bacteria. The active enzyme is a dimeric protein, both subunits having molecular weights of about 62,000....
