Bacillus subtilis can use either nitrate or nitrite as a sole source of nitrogen. The isolation of the nasABCDEF genes of B. subtilis, which are required for nitrate/nitrite assimilation, is reported. The probable gene products include subunits of nitrate/nitrite reductases and an enzyme involved in the synthesis of siroheme, a cofactor for nitrite reductase.
枯草芽孢杆菌能够将硝酸盐或亚硝酸盐作为唯一的氮源。本文报道了枯草芽孢杆菌中参与硝酸盐/亚硝酸盐同化作用的nasABCDEF基因的分离情况。可能的基因产物包括硝酸盐/亚硝酸盐还原酶的亚基以及一种参与亚硝酸盐还原酶辅因子——高铁血红素合成的酶。
