Abstract
is virulent or avirulent. Deciphering its mode of action might thus lead to new ways of fighting infections. Here we used X-ray crystallography to solve the three-dimensional structure of the domain that precedes the enzymatic moiety and identified features that regulate BvgS activity. As many sensor-kinases of the BvgS family harbor homologous domains, the mechanism unveiled here might be of general relevance.
