The Glutamine-493 residue on the spike protein is an important residue in showing the differences in strength between ACE2 and the minibinders <ref name="Longxing">PMID:32907861</ref>. ACE2 does not make use of this residue when <scene name='10/1075250/Q493_ace2/12'>binding to the RBD</scene>. The nearest residues of ACE2, Gln35 and Lys31, do not form any interaction on Gln493 of the spike protein. The AHB2 minibinder, instead forms a <scene name='10/1075251/Q493-ahb2/1'>hydrogen bond</scene> on the Gln493 of the spike protein residue of the spike protein with its Glu41, increasing affinity to the spike protein. LCB1 forms <scene name='10/1075250/Q493_lcb1/9'>two hydrogen bonds</scene> on Gln493 of the spike protein using its Asp17 and Arg14 residues, giving it the highest affinity based on the Gln493 residue. However, these interactions are not required. LCB1 forms <scene name='10/1075251/Q493-lcb3/1'>no interactions</scene> with the Gln493 residue of the RDB previously mentioned, yet it still has a higher affinity to the RBD than AHB2.

Similarly, ~~ACE2 forms a hydrogen bond with the Lys417 from its Asp30 residue.~~ LCB1~~, however,~~ forms two hydrogen bonds with both the Lys417 and Arg403 of the spike protein from its Asp30 residue. This is a very strong interaction, further contributing to the high affinity of LCB1 to the spike protein<ref name="Longxing">PMID:32907861</ref>.

Similarly, LCB1 forms <scene name='10/1075250/D30_lcb1/3'>two hydrogen bonds</scene> with both the Lys417 and Arg403 of the spike protein from its Asp30 residue. This is a very strong interaction, further contributing to the high affinity of LCB1 to the spike protein<ref name="Longxing">PMID:32907861</ref>.
