Abstract excerpt

In a structural model of the 2-kinase domain of the bifunctional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase based on the analogy with adenylate kinase, Lys-174, Asp-179 and Asp-191 residues are located in the putative active site. Asp-179 and Asp-191 are conserved in all known 6-phosphofructo-2-kinase sequences. In contrast, Lys-174 is conserved except in a yeast isoenzyme, fbp26, where it is...
