Regulation summary diagram for yadK

Summary:
yadCKLMhtrEecpDyadN is a putative chaperone-usher fimbrial operon in E.coli K-12 [Korea10]. The operon is cryptic under normal laboratory conditions but when constitutive expression is induced in a strain that lacks the type 1 fimbrial complex the yad operon promotes biofilm formation in minimal media on a variety of abiotic surfaces and produces surface fimbrial structures that can be observed microscopically [Korea10]. Expression of the yad operon is negatively regulated by H-NS [Korea10].
