A heat-inducible Hsp70 promoter drives expression of a constitutively active form of btl in which the ligand-binding extracellular domain has been replaced with the dimerization domain of the bacteriophage λ cI repressor (to induce constitutive dimerization of the encoded protein).
construct_comment: See report for T:λ\cIDD.
report comment: Produces active form of btl with λ\cIDD dimerization domain; not dependent upon ligand-induced dimerization and thus results in constitutive activity.
