Figure S1. Product ion spectra derived from (a) ion/ion reaction between [ARAAARA+2Na]2+ and [wrkH]-, and (b) CID of [ARAAARA+wrk+2Na-H]+ complex. (Lightning bolt denotes ions subjected to
collisional activation. Circles (°) denote water losses.)

Figure S2. Product ion spectra derived from CID of (a) [AKAAAKA+wrk+H]+ complex, and (b)
[AKAAARA+wrk+H]+ complex. (Lightning bolt denotes ions subjected to collisional activation. Circles
(°) denote water losses.)

Figure S3. Product ion spectra derived from (a) ion/ion reaction between [RARARAA+3H]3+ and [wrkH]-, and (b) CID of [RARARAA+wrk+2H]2+ complex. (Lightning bolt denotes ions subjected to
collisional activation. Asterisks (*) denote ammonia losses whereas circles (°) denote water losses.)
