Characterization of a HMT2-like enzyme for sulfide oxidation from Pseudomonas putida.
The open reading frame pp0053, which has a high homology with the sequence of mitochondrial sulfide dehydrogenase (HMT2) conferring cadmium tolerance in fission yeast, was amplified from Pseudomonas
Menaquinone reduction by an HMT2-like sulfide dehydrogenase from Bacillus stearothermophilus.
The gene-encoding HMT2-like sulfide dehydrogenase from Bacillus stearothermophilus JCM2501 was amplified and expressed in Escherichia coli and the enzymatic features were examined and sulfide oxidation via MK in the cellular membrane of Gram-positive bacteria was certified.
Sulfide oxidation in gram-negative bacteria by expression of the sulfide-quinone reductase gene of Rhodobacter capsulatus and by electron transport to ubiquinone.
Results indicate that sulfide oxidation in this strain occurs via the quinone pool in vivo, and that this sulfide-quinone reductase (SQR) in particular utilizes ubiquinone as a more appropriate electron acceptor than menaquinone or demetylmenaquinone.
