Behind the versatile nature of prokaryotic energy metabolism is a set of redox proteins
having a highly modular character. It has become increasingly recognized that a limited …

SoxAX cytochromes are heme-thiolate proteins that play a key role in bacterial thiosulfate
oxidation, where they initiate the reaction cycle of a multi-enzyme complex by catalyzing the …

In this work we identified the gene for the tetrathionate‐forming thiosulfate dehydrogenase
(TsdA) from the purple sulfur bacterium Allochromatium vinosum by sequence analysis and …

Thiosulfate dehydrogenases are bacterial cytochromes that contribute to the oxidation of
inorganic sulfur. The active sites of these enzymes contain low-spin c-type heme with Cys …

Although the oxidative condensation of two thiosulfate anions to tetrathionate constitutes a
well documented and significant part of the natural sulfur cycle, little is known about the …

The enzymes of the thiosulfate dehydrogenase (TsdA) family are wide-spread diheme c-type
cytochromes. Here, redox carriers were studied mediating the flow of electrons arising from …

The diversity and phylogenetic significance of bacterial genes in the environment has been
well studied, but comparatively little attention has been devoted to understanding the …

Thiosulfate dehydrogenases (TsdAs) are bidirectional bacterial di-heme enzymes that
catalyze the interconversion of tetrathionate and thiosulfate at measurable rates in both …

Thiosulfate dehydrogenase (TsdA) catalyzes the oxidation of two thiosulfate molecules to
form tetrathionate and is predicted to use an unusual cysteine-ligated heme as the catalytic …

In biological energy conversion, cross-membrane electron transfer often involves an
assembly of two hemes b. The hemes display a large difference in redox midpoint potentials …
