北海道大学，札幌)（收到发表，1968年9月4日）众所周知，亚硫酸盐还原是硫酸盐还原细菌（1,2）和硫酸盐同化生物(3)将硫酸盐还原为硫化物的一个步骤。在后一种生物中，负责将亚硫酸盐还原为硫化物的酶已经获得了高度纯化的状态（4-6），并以单一蛋白质为特征，亚硫酸盐还原酶[硫化氢：NADP氧化还原酶，EC 1.8]。1.2]。然而，硫酸盐还原细菌的酶系统只被部分纯化(7)。本文报道了硫酸盐还原菌Desulfovibriovulgaris制备的酶还原亚硫酸盐过程中三硫酸盐中间产物的形成。
Hokkaido University, Sapporo)(Received for publication, September 4, 1968) Sulfite reduction is known to be a step of the reduction of sulfate to sulfide in both sulfate-reducing bacteria (1, 2) and sulfateassimilating organisms (3). In the latter organisms, the enzymes responsible for the reduction of sulfite to sulfide have been obtained in highly purified states (4-6) and characterized as single proteins, sulfite reductases [hydrogen-sulfide: NADP oxidoreductase, EC 1.8. 1.2]. However, the enzyme system of sulfate-reducing bacteria has been only partially purified (7). The present communication reports on intermediary formation of trithionate in the course of sulfite reduction by an enzyme preparation froma sulfate-reducing bacterium, Desulfovibriovulgaris.
