Reconstituted Complex
An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

Grafting of features of cystatins C or B into the N-terminal region or second binding loop of cystatin A (stefin A) substantially enhances inhibition of cysteine proteinases.
Replacement of the three N-terminal residues preceding the conserved Gly of cystatin A by the corresponding 10-residue long segment of cystatin C increased the affinity of the inhibitor for the major lysosomal cysteine proteinase, cathepsin B, by approximately 15-fold. This tighter binding was predominantly due to a higher overall association rate constant. Characterization of the interaction with an inactive Cys29 ... [more]
