Extended Data Fig. 4: In vitro enzyme reaction of CcbD with amine-containing substrates.
(A) Structures of substrates and products. (B) LC-MS charts of the enzyme reactions of CcbD with various amine-containing products. Blue, orange, and gray charts represent EIC = 116, EICs of amine-containing substrates, and EICs of product masses, respectively. Hilic column and C18 column were used to separate the enzyme reaction products.
