초록
3'-Phosphoadenosine-5'-phosphosulfate (PAPS) is the obligate cosubstrate and source of the sulfonate group in the chemoenzymatic synthesis of heparin, a commonly used anticoagulant drug. Previously, using ATP as the substrate, we had developed a one-pot synthesis to prepare PAPS with 47% ATP conversion efficiency. During the reaction, 47% of ATP was converted into the by-product, ADP. Here, to increase the conversion ratio of ATP to PAPS, an ATP regeneration system was developed to couple with PAPS synthesis. In the ATP regeneration system, the chemical compound, monopotassium phosphoenolpyruvate (PEP
