In this work we show by high resolution tandem mass spectrometry that CstR is readily modified by selenite ( SeO3 ( 2 - ) ) or tellurite ( TeO3 ( 2 - ) ) to form a mixture of intersubunit disulfides and selenotrisulfides or tellurotrisulfides , respectively , between Cys31 and Cys60 ' .
 Chemical: selenite; Chemical: SeO3 ( 2 - ); Chemical: tellurite; Chemical: TeO3 ( 2 - ); Chemical: disulfides; Chemical: selenotrisulfides; Chemical: tellurotrisulfides; Chemical: Cys31; Chemical: Cys60
