ribokinase/pfkB superfamily: Kinases that accept a wide variety of substrates, including carbohydrates and aromatic small molecules, all are phosphorylated at a hydroxyl group. The superfamily includes ribokinase, fructokinase, ketohexokinase, 2-dehydro-3-deoxygluconokinase, 1-phosphofructokinase, the minor 6-phosphofructokinase (PfkB), inosine-guanosine kinase, and adenosine kinase. Even though there is a high degree of structural conservation within this superfamily, their multimerization level varies widely, monomeric (e.g. adenosine kinase), dimeric (e.g. ribokinase), and trimeric (e.g THZ kinase).
