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.

Yeast geranylgeranyltransferase type-II: steady state kinetic studies of the recombinant enzyme.

Witter DJ, Poulter CD

Rab proteins in mammalian cells, or Ypt1p and Sec4p in yeast, regulate vesicular traffic. Prenylation of these small GTP-binding proteins is required for membrane attachment and subsequent biological activity. Yeast protein geranylgeranyltransferase type-II (PGGTase-II) catalyzes the prenylation of Ypt1p in the presence of an escort protein, Msi4p. The genes encoding the alpha-(BET4) and beta-(BET2) subunits of PGGTase-II were translationally coupled ... [more]
