a, HPLC traces of hydrolysed/derivatized amino acid obtained after incubation of l-allo-Ile-S-CmaD with CmaB and with CmaB plus CmaC. b, HPLC traces of hydrolysed/derivatized amino acid obtained after incubation of l-Val-S-CmaD with CmaB and with CmaB plus CmaC. c, Iron, 
-KG, O2 and Cl- are required for the CmaB reaction. d, Incorporation of 36Cl- into 
-Cl-l-allo-Ile-S-CmaD by CmaB. e, Mass spectrometric analysis of the isoindole derivatives of -Cl-l-allo-Ile and CMA hydrolysed from CmaD after reaction with CmaB and CmaC, respectively.
