Hemolysin B - HlyB
HlyB is part of the hemolysin secretion system ([http://2011.igem.org/Team:UNICAMP-EMSE_Brazil/Project#Device_3:_Secretion_system Device 3, Protein Secretion System]), very important to export the proteins produced inside bacteria and that must act in targets outside (such as IL-12 and IL-10). HlyB acts as a ATP-binding cassette, and recognizes the substrate via its secretion signal (like HlyA) and is responsible for the specificity of the secretion system process. This system is composed of 4 essential parts: the C-terminal signal sequence of alpha-hemolysin (HlyA, which will be linked to the export target protein), the two specific translocator proteins HlyB and HlyD and the outer membrane protein [BBa_K554009 TolC].

Usage and Biology
You can see a representation of this device acting in the schema below:
Representation of device 3, the protein secretion system, in a Jedi bacteria that contains Device 1 (Adrenaline sensor/IL-12 producer). To export a protein, the bacteria must have the HlyD, HlyB and TolC proteins and the target protein must have a signal sequence (HlyA tail). In this case, the target protein to be secreted is IL-12.
