Co-purification

An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

Recombinant expression and evaluation of the lipoyl domains of the dihydrolipoyl acetyltransferase component of the human pyruvate dehydrogenase complex.

Liu S, Baker JC, Andrews PC, Roche TE

The subunits of the dihydrolipoyl acetyltransferase (E2) component of mammalian pyruvate dehydrogenase complex (PDC) associate to form a large inner core with a protruding structure composed of three globular domains connected by mobile linker regions. This exterior region of E2 includes two lipoyl domains which engage not only in the intermediate reactions of the complex but also have integral roles ... [more]
