実験手順

The enzyme L-aspartase, immobilized by the process of this invention, can be used to convert diammonium fumarate to L-aspartate in 90% yield at pH 7 and 25° C. The immobilized L-aspartase enzyme polymer can be used over and over again to convert fumarate to L-aspartate without significant loss in activity.
