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.

Interactions between pyruvate carboxylase and other mitochondrial enzymes.

Fahien LA, Davis JW, Laboy J

Although pyruvate carboxylase associated with both mitochondrial aspartate aminotransferase and malate dehydrogenase, it had a higher affinity for the amino-transferase. Furthermore, the aminotransferase enhanced dissociation of malate dehydrogenase from pyruvate carboxylase. Glutamate dehydrogenase did not associate with pyruvate carboxylase alone, but it apparently associated with the pyruvate carboxylase-aminotransferase complex, and malate dehydrogenase associated with the resulting ternary complex. Citrate synthase ... [more]
