TABLE 2.
Proton and carbon chemical shift (600 MHz, 298 K)
Chemical shifts are with respect to internal acetone (1H 2.225 ppm, 13C 31.45 ppm) measured for the reaction products between UDP-GlcNAc and Mg534 in the presence of NaBH4 (UDP-β-6-deoxy-IdoNAc and UDP-α-QuiNAc) or in the presence of Mg535 and NADPH (UDP-β-RhaNAc).
