Structural stability of adenylate kinase from the sulfate-reducing bacteria Desulfovibrio gigas.

A novel adenylate kinase (AK) has recently been purified from Desulfovibrio gigas and characterized as a Co(2+)/Zn(2+)-containing enzyme: this is an unusual characteristic for AKs from Gram-negative bacteria, in which these enzymes are normally devoid of metals. Here, we studied the conformational stability of holo- and apo-AK as a function of temperature by differential scanning calorimetry (D...

Isolation of sulfate-reducing bacteria from Tunisian marine sediments and description of Desulfovibrio bizertensis sp. nov.

Several strains of sulfate-reducing bacteria were isolated from marine sediments recovered near Tunis, Korbous and Bizerte, Tunisia. They all showed characteristics consistent with members of the genus Desulfovibrio. One of these strains, designated MB3(T), was characterized further. Cells of strain MB3(T) were slender, curved, vibrio-shaped, motile, Gram-negative, non-spore-forming rods. They ...

On the mechanism of adenylyl sulfate reductase for the sulfate-reducing bacterium, Desulfovibrio vulgaris.

NADH dehydrogenases have been isolated in a low-molecular weight form (56,500) from both low-iron and normal-iron grown cells of Azotobacter vinelandii. Unlike low-molecular weight forms of NADH dehydrogenases reported from mammalian mitchondria, the enzymes in this study have not undergone any unusual alterations in various reactivities with substrates and electron acceptors. The NADH dehydrog...
