Answer

Usually, dephosphorylation of fructose-1,6 bisphosphate is catalysed by fructose-1,6 bisphosphatase and condensation of dihydroxyacetone phosphate and glyceraldehyde-3-phosphate into fructose 1,6-bisphosphate is catalysed by aldolase. These two reactions gluconeogenic pathway. occur in the Combining these two reactions by a single enzyme would actually skip a reaction. In this way, some archaebacteria speed the gluconeogenic pathway.
