[Objective] Poly(butylene adipate-co-butylene 2,5-furandicarboxylate) (PBAF) is a biodegradable furan-based copolyester plastic. In the chemical synthesis of PBAF, the randomness of oligomer polymerization leads to the formation of complex polymers, such as block copolymers, random copolymers, and alternating copolymers. In this study, dimethyl furan-2,5-dicarboxylate (FDME) and 1,4-butanediol (BDO) were used as substrates to synthesize bis-BDO ester by enzymatic reaction to provide the bioplastic precursor for controllable polymerization and avoid complex by-products. [Methods] RgPETase from Rhizobacter gummiphilus was heterogeneously expressed in Escherichia coli BL21(DE3). RgPETase exhibited acyltransferase activity for FDME and BDO. The reaction conditions including pH, temperature, content of BDO (as both substrate and solvent), and amount of enzyme for the synthesis of bis-BDO ester were optimized. [Results] The optimum reaction conditions of RgPETase were pH 8.0, BDO content of 30%, and reaction temperature within the range of 25–30 ℃. Under the optimum conditions (30 ℃ and enzyme concentration of 6 μmol/L), RgPETase can catalyze 10 mmol/L FDME to produce (2.96±0.01) mmol/L bis-BDO ester. [Conclusion] RgPETase exhibits high acyltransferase activity and catalyzes the generation of bis-BDO ester from FDME via acyl transfer reaction under mild conditions, which provides a green and sustainable approach for synthesizing the precursor of PBAF.
