Identification of c-di-AMP binding proteins. Detection of in vitro c-di-AMP binding was performed with c-di-AMP immobilized to an agarose matrix. This was incubated with cell extract from M. pneumoniae. The c-di-AMP bound proteins were eluted with free c-di-AMP and analyzed by SDS-polyacrylamide gel electrophoresis and visualized by silver staining. Proteins were identified by mass spectrometry. Arrows show mass spectrometry analyzed bands. E, elution fraction; +, agarose coupled with c-di-AMP; -, agarose coupled with ethanolamine.
