In silico evidence for the horizontal transfer of gsiB, a σ(B)-regulated gene in gram-positive bacteria, to lactic acid bacteria Vrije Universiteit Brussel
gsiB, coding for glucose starvation-inducible protein B, is a characteristic member of the σ(Β) stress regulon of Bacillus subtilis and several other Gram-positive bacteria. Here we provide in silico evidence for the horizontal transfer of gsiB in lactic acid bacteria that are devoid of the σ(Β) factor.
