Automated injection of slurry samples in flow-injection analysis [PDF]
, 1995 Two types of injectors are described for introducing solid samples as slurries in flow analysis systems. A time-based and a volume-based injector based on multitube solenoid pinch valves were built, both can be characterized as hydrodynamic injectors ...

AcrB-AcrA Fusion Proteins That Act as Multidrug Efflux Transporters [PDF]
Journal of Bacteriology, 2016 ABSTRACT The AcrAB-TolC system in Escherichia coli is an intrinsic RND-type multidrug efflux transporter that functions as a tripartite complex of the inner membrane transporter AcrB, the outer membrane channel TolC, and the adaptor protein AcrA.

Functional relevance of AcrB Trimerization in pump assembly and substrate binding.
PLoS ONE, 2014 AcrB is a multidrug transporter in the inner membrane of Escherichia coli. It is an obligate homotrimer and forms a tripartite efflux complex with AcrA and TolC. AcrB is the engine of the efflux machinery and determines substrate specificity.
