Salt stress induction of glutamyl endopeptidase biosynthesis in Bacillus intermedius.

Bacteria from the genus Bacillus have evolved complicated regulatory networks to be protected from various environmental stresses, including sudden increase in salinity. Among these regulatory mechanisms is the DegS-DegU signal transduction system, which controls degradative enzyme synthesis and is involved in sensing salt stress in Bacillus subtilis. We report the study of biosynthesis regulation of Bacillus intermedius glutamyl endopeptidase under salt stress conditions.
