contrary to the phenylalanine-alpha-ketoglutarate reaction , which is probably of little importance in vivo when catalyzed by this enzyme , the direct ketoglutarate-free transamination between aspartate and the aromatic alpha-ketoacid is likely to represent a physiological function in regulating , at least partially , the balance between biosynthetic pathways for aromatic aminoacids and aspartate , for instance by maintaining similar ratios between the aminoacid and its ketoacid partner in both cases .
