Sulfur metabolism in Thiobacillus denitrificans evidence for the presence of a sulfite reducatase activity.

Abstract

The relatively high specific sulfite reductase activity of 25 mU/mg protein was found in extracts from Thiobacillus dentrificans. The absorption spectrum of the partially pruified enzyme was similar to the siroheme containing sulfite reductases from other sources. It is suggested that the T. denitrificans sulfite reductase may function during the oxidation of reduced sulfur compounds.
