Reversed phase HPLC analysis of reaction mixtures from transglycosylation reactions. Chromatograms 1, 2 and 3 were the blank medium with only α-CD (205 mM) and CGTase at 0 h, 2 h and 12 h, respectively (no acceptor). Chromatograms 4 and 5 contained α-CD, 410 mM as initial concentration and G1P (I, II and III- monopropionate isomers – IV, V and VI – dipropionate isomers) without CGTase at 0 h and 24 h. Chromatograms 6, 7 and 8 contained G1P, α-CD (410 mM) and CGTase at 0 h, 2 h and 12 h. Chromatograms 9, 10 and 11 from a reaction containing α-CD (410 mM), G2A (VIII and IX) and CGTase at 0 h, 8 min and 2 h of reaction time.
