Reaction Conditions:

with glucuronokinase from Arabidopsis thaliana;pyrophosphatase from E_. coli;UDP-sugar pyrophosphorylasegene from Arabidopsis thaliana;ATP;magnesium chloride in aq. buffer at 37; pH=8;Enzymatic reaction;

Steps:

1 4.6. One-pot three-enzyme synthesis of UDP-GlcA and UDP-GalA

General procedure: Preparative-scale synthesis of UDP-GlcA and UDP-GalA wereperformed in a 20 mL reaction system containing 50 mM pH 8.0TriseHCl buffer, 20 mM GlcA or GalA, 22 mM ATP, 22 mM UTP,20mMMgCl2, and 0.1e2mg of different enzymes. For the synthesisof UDP-GlcA, 0.6 mg of AtGlcAK, 0.4 mg of AtUSP, and 0.1 mg of EcPpA20 were employed; for the synthesis of UDP-GalA, 2 mg ofBiGalK, 0.4 mg of AtUSP, and 0.1 mg of EcPpA were employed. Thereaction mixtures were incubated at 37 C for 4e12 h with gentleshaking. The generation of UDP-sugars were monitored by TLC(Isopropanol:NH4OH:H2O7:3:2). After 90% of monosaccharidesconverted into UDP-sugar, reactions were quenched by boiling for5 min, centrifuged to remove precipitants, and concentrated forseparation. The separation of UDP-sugars from the reaction mixtureswere performed by gel filtration (Bio-Gel P2, Bio-Rad), fractionscontaining products were pooled and lyophilized. Digestion ofnucleotides by alkaline phosphatase and further P2 purificationwere applied to achieve minimum 95% purity. The final productswere lyophilized and characterized by HRMS and NMR.
