Selenite and tellurite form mixed seleno- and tellurotrisulfides with CstR from Staphylococcus aureus†
Abstract
Staphylococcus aureus CstR (CsoR-like sulfur transferase repressor) is a member of the CsoR family of transition metal sensing metalloregulatory and
, respectively. Here, we investigate if CstR performs similar chemistry with related
and
. The modification of Cys31 also drives an allosteric switch that negatively regulates DNA binding while
