Crystallographic data demonstrated the existence of an unusual allosteric site that can bind both GlcNAc6P and GlcNol6P, implying that the homotropic activation of this enzyme arises from the occupation of the allosteric site by the substrate.
ITC experiments revealed two different binding sites with distinctive thermodynamic signatures: a single binding site per monomer for the allosteric activator N-acetylglucosamine 6-phosphate (GlcNAc6P) and two binding sites per monomer for the transition-state analog 2-amino-2-deoxy-D-glucitol 6-phosphate (GlcNol6P). This study describes the regulatory mechanism of SdNagBII using enzyme kinetics, isothermal titration calorimetry (ITC), and X-ray crystallography. Additionally, we found that the sigmoidal kinetics of SdNagBII cannot be explained by the existing models of homotropic activation. denitrificans (SdNagBII) are special examples of what constitute non-homologous isofunctional enzymes due to their convergence, not only in catalysis, but also in cooperativity and allosteric properties.

Right your observations in the chart below. With your partner, observe the seven limbs in the picture that was given to you. Answer: _ Compar ing Homologous Structures : Purpose: In this activity you will observe parts of different animals and look for evidence that these animals are related to each other (that is, that they could have evolved from the same common ancestor). A house cat and a lion evolved from the same ancestor but no longer look alike (the house cat is much smaller than the lion). A whale and a fish both have fins to swim underwater, however, a whale is a mammal and a fish isn’t. A poisonous spider and a poisonous snake both have venom sacs. Evolved from different ancestors, but because they were placed in the same environment, they have the same function. Evolved from the same ancestor but now have different functions.
