Comments concerning this interaction

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey produced as a recombinant fusion protein in bacterial system.

cid, cal1 and His4 interact together as part of a complex.

Proteins were coexpressed in bacterial cells, affinity purified by virtue of the His tag and further purified by gel filtration.
