Function
[MALE_ECOLI] Involved in the high-affinity maltose membrane transport system MalEFGK. Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides.
Publication Abstract from PubMed
The production of high-quality crystals is the main bottleneck in determining the structures of proteins using X-ray crystallography. In addition to being recognized as a very effective solubility-enhancing fusion partner, Escherichia coli maltose-binding protein (MBP) has also been successfully employed as a `fixed-arm' crystallization chaperone in more than 100 cases. Here, it is reported that designed ankyrin-repeat proteins (DARPins) that bind with high affinity to MBP can promote the crystallization of an MBP fusion protein when the fusion protein alone fails to produce diffraction-quality crystals. As a proof of principle, three different co-crystal structures of MBP fused to the catalytic domain of human dual-specificity phosphatase 1 in complex with DARPins are reported.
