Structure of IraD Bound RssB

Caption

A false-color structure of RssB (pink and cyan) -- a protein that specifically recognizes a critical stress-response master regulator in bacteria and delivers it to the recycling machinery somewhat like a recycling truck -- bound to IraD (green) -- a factor that inhibits RssB activity. Both lobes of RssB, which are connected by a flexible linker (magenta) contact IraD in a "hug."
