Inhibitors bind with the active or allosteric site of HIV RT based on their chemical nature whether they are analogs of nucleoside or non-nucleoside, respectively.
A recent study using a crystal structure of the catalytic domain of GLS1 complexed with DON reported that it covalently binds with the active site Ser286 and interacts with residues such as Tyr249, Asn335, Glu381, Asn388, Tyr414, Tyr466, and Val484.

In addition, Hirudin is the most potent natural inhibitor of thrombin, which possesses a specific activity to bind with the active site and fibrinogen-binding exosite 1 of thrombin and cleave fibrinogen and PAR-1 (Table 2) [ 83].
Increase in catalytic activity with increasing temperature could be rationalized that at higher temperature, phenyl ring of the borane moiety cannot bind with the active metal center which is beneficial for better activity.
It is directly related with the competition abilities of hydrogen ions with metal ions to bind with the active sites on the biosorbent surface.
Having a structure more similar to that of L-tyrosine than that of 4-TBP, RD was speculated to bind with the active center of tyrosinase.
Thus, we consider the fact that clusterin, as a chaperon molecule, has been found to bind with the active form of Bax under apoptotic stimuli inhibiting its dimerization in the mitochondria and block apoptosis.
Having a structure similar to that of L-tyrosine, 4-TBP is reported to be able to bind with the active center of tyrosinase and work as an inhibitor [ 24].
To visualize the protein protein interaction network of the protein PF0847, STRING was employed, and the obtained network is shown in Figure 8. Continuing with the STRING results, we found that geneticin bound to the eubacterial 16S rRNA A-site (PDB code: 1MWL) binds with the active site of the target protein PF0847 (Fig. 9).
