Zusammenfassung: 
During cultivation in the presence of trehalose Streptomyces reticuli expresses an inducible. highly specific trehalose uptake system that is absent in Streptomyces lividans. A palmitated trehalose-binding protein was identified in the cytoplasmic membrane of mycelia, extracted with the detergent Triton X-100 and purified using a trehalose affinity matrix. Immunological studies showed that within S. reticuli the synthesis of the ATP-binding protein MsiK is induced by trehalose. The data suggest that MsiK assists the trehalose ABC transporter, like the previously described ABC transport systems for maltose and cellobiose/cellotriose, respectively.
