Extended Data Fig. 6. In situ labelling of C. difficile with a hydrazine probe and gel-based profiling of D-proline reductase activity.

(a) Labeling schematic of hydrazine probe with PrdA of D-proline reductase. (b) Representative gel-based labelling profiles for C. difficile in the absence and presence of E. faecalis supernatant. Gel representative of three separate experiments. For Gel source data, see Supplementary Fig. 1. (c) Corresponding expression profiles after Coomassie staining.
