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.

Interaction of cytochrome c with cytochrome bc1 complex of the mitochondrial respiratory chain.

Broger C, Nalecz MJ, Azzi A

The binding of cytochrome c to the cytochrome bc1 complex of bovine heart mitochondria was studied. Cytochrome c derivatives, arylazido-labeled at lysine 13 or lysine 22, were prepared and their properties as electron acceptors from the bc1 complex were measured. Mixtures of bc1 complex with cytochrome c derivatives were illuminated with ultraviolet light and afterwards subjected to polyacrylamide gel electrophoresis. ... [more]
