The enzyme adenylosuccinate synthase carries out the reaction by the addition of aspartate to IMP and requires the input of energy from a phosphoanhydride bond in the form of guanosine triphosphate (GTP).
The enzyme adenylosuccinate synthase executes the reaction by combining aspartate with IMP and necessitates the input of energy from a phosphoanhydride bond in the form of guanosine diphosphate (GDP).
