CoASH associates with a high-affinity, catalytic site and with a secondary, low-affinity site that overlaps with the antibiotic binding pocket. The binding of CoASH to the high-affinity site occurs with a small, unfavorable enthalpy and a favorable entropy. Binding to the second site is highly exothermic and is accompanied by an unfavorable entropic contribution. The presence of an aminoglycoside alters the binding of CoASH to the enzyme dramatically such that the binding occurs with a favorable enthalpy and an unfavorable entropy. This is irrespective of which aminoglycoside is the cosubstrate and occurs without a significant change in the affinity of CoASH for the enzyme. The presence of antibiotics eliminates binding of CoASH to the second site

-
enzyme displays molecular size-dependent stoichiometry where binding stoichiometries are 1.5-2.0 for small antibiotics and 1.0 for larger. Antibiotic-enzyme interaction occurs with a favorable enthalpy and a compensating unfavorable entropy. The presence of coenzyme A significantly increases the affinity of the antibioticthe enthalpy of binding becomes more favored by 1.7-10.0fold in the presence of the cosubstrate CoASH, while the entropy becomes 2.0-22.5fold less favored. The overall free energy change is still only 1.0-1.9 kcal/mol from binary to ternary for all antibiotics tested, similar to those for other aminoglycoside-modifying enzymes
