== Publication Abstract from PubMed ==
 +
A fluorobody is a manmade hybrid molecule that is composed of green fluorescent protein (GFP) and a fragment of antibody, which combines the affinity and specificity of an antibody with the visibility of a GFP. It is able to provide a real-time indication of binding while avoiding the use of tags and secondary binding reagents. Here, the expression, purification and crystal structure of a recombinant fluorobody for TLH (thermolabile haemolysin), a toxin from the lethal food-borne disease bacterium Vibrio parahaemolyticus, are presented. This is the first structure of a fluorobody to be reported. Crystals belonging to space group P43212, with unit-cell parameters a = b = 63.35, c = 125.90 A, were obtained by vapour diffusion in hanging drops and the structure was refined to an Rfree of 16.7% at 1.5 A resolution. The structure shows a CDR loop of the antibody on the GFP scaffold.
