In Silico Evidence for the Horizontal Transfer of gsiB, a σΒ-Regulated Gene in Gram-Positive Bacteria, to Lactic Acid Bacteria

摘要

gsiB, coding for glucose starvation-inducible protein B, is a characteristic member of the σΒ 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 σΒ factor.
