General stress proteins inBacillus subtilis

Bacillus cells frequently faced with various adverse environmental factors in nature have evolved different adaptational strategies. The induction of stress proteins is an essential component of this adaptational network. In Bacillus subtilis there are two groups of stress proteins. The first group is factor specific, whereas the second group is induced by growth restrictive conditions in general. The relationship between the stringent response and the induction of stress proteins is discussed.
