The nasB operon and nasA gene are required for nitrateitrite assimilation in Bacillus subtilis.

摘要

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 nitrateitrite assimilation, is reported. The probable gene products include subunits of nitrateitrite reductases and an enzyme involved in the synthesis of siroheme, a cofactor for nitrite reductase.
