Hijacked supplies for pathogens

ns by attaching an AMP molecule to Rab1. "The permanent activation of Rab1 by DrrA could ensure increased material transport in the direction of the Legionella containing compartment and hence support its survival," concludes Aymelt Itzen from the Max Planck Institute of Molecular Physiology.

"These results represent an example of how the molecular analysis of bacterial diseases can help us not only to understand the cellular mechanisms involved in an infection, but also the functioning of healthy cells," explains Roger Goody from the Dortmund Institute. In the case of Legionnaire's disease, the study of the bacterial protein DrrA reveals how a human regulatory protein (Rab1) is activated in a targeted way and maintained in an active state. This raises the question as to whether Legionella devised this kind of regulation or whether healthy cells can also control material transport in a similar but hitherto unknown way.
