Fig. 2. Functional characterization of GuApiGT.

Fig. 2

a Catalytic function of GuApiGT using 1 and 2 as sugar acceptors. The acceptors were incubated with GuApiGT and an UDP-Api supply system (UDP-GlcA, UAXS, NAD+) in pH 8.0 (50 mM NaH2PO4-Na2HPO4 buffer) at 37 °C for 3 h. b (-)-ESI-MS and MS2 spectra of 1a. For compounds identification, see Fig. 1.
