lab and exd bind DNA cooperatively; neither binds DNA on its own in this assay.

Interaction in vitro; proteins produced as a recombinant fusion proteins in bacterial system.

Various combinations of lab and exd were mixed with [32]P labeled DNA. DNA-protein complexes observed by EMSA were used to deduce protein-protein interactions.

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

exd stimulates strong binding of lab DNA by lab. Alone, neither lab nor exd binds to lab DNA.

Various combinations of hth, lab and exd proteins were mixed with [32]P labeled lab DNA. DNA-protein complexes observed by EMSA were used to deduce protein-protein interactions.

Interaction in vitro; proteins produced by in vitro transcription/translation.

exd, hth and lab, in various combinations, were mixed with [32]P labeled DNA. DNA-protein complexes observed by EMSA, corresponding to lab-exd heterodimers and lab-exd-hth heterotrimers, were used to deduce protein-protein interactions.

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

exd and lab form heterodimers that bind DNA. Neither binds DNA alone.
