Phosphate-induced enhancement of fumarate production from a CO2 and pyruvate with the system of malate dehydrogenase and fumarase
The phosphate-addition induced improvement of the synthesis yield of fumarate from CO2 and pyruvate in an aqueous medium using a multi-biocatalytic system of ME from Sulfobus tokodaii and FUM from porcine heart in the presence of NADH was demonstrated.
