S. aureus strains that are methicillin resistant have a mecA gene that encodes for a unique penicillin-binding protein that has decreased affinity for β-lactam antibiotics (Lambert 2005).
In contrast, the PLB mutant with the loss-of-function L31A mutation has decreased binding affinity for SERCA2a, thus cross-linking weakly to the WT-PLB-tethered SERCA2a, and only marginally affected the activity of SER-20G-PLB.
Resistance to thyroid hormone (RTH) is a clinical syndrome in which most affected patients have a mutant TRβ allele that encodes a mutant receptor which has decreased binding affinity for T3 leading to decreased transcriptional activity [27].
i) In the Gli-B2-derived α-gliadins analyzed, none of the DQ2 epitopes are present due to a single amino acid deletion in the region encoding the DQ2-Glia-α1 and DQ2-Glia-α2 epitopes, which generates a peptide that has decreased binding affinity for HLA-DQ2 and is no longer recognized by T cells.
Many of these programs have evolved, and effectively designed MCH antagonists having decreased hERG-binding affinity have emerged.

Hp22 is reported to have decreased binding affinity for free haemoglobin [16], [17] and has been associated with markers of oxidant stress [7], [18], [19] and iron delocalisation [20].
Second, Scp1 variant (C618S/C680S) appeared to have decreased binding affinity with Sre1.
In addition, in R1 position, –CHF2 group has increased the binding affinity and decreased the entropy contribution, while –CF3 group displayed completely opposite effect when bound with SQR.
N59D uniquely causes PEP binding affinity to decrease, while having little effect on the binding affinity of MgADP.
