Ligand-modulated parallel mechanical unfolding pathways of maltose-binding proteins.
Protein folding and unfolding are complex phenomena, and it is accepted that multidomain proteins generally follow multiple pathways. Maltose-binding protein (MBP) is a large (a two-domain, 370-amino acid residue) bacterial periplasmic protein involved in maltose uptake. Despite the large size, it has been shown to exhibit an apparent two-state equilibrium unfolding in bulk experiments. Single-...
متن کاملEngineered Derivatives of Maltose-Binding Protein
Maltose-binding protein (MBP), a member of the periplasmic binding protein family of Gram negative bacteria, is a versatile substrate for protein engineering. In common with other periplasmic proteins, it is extremely protease resistant, and it can fold properly in both the cytoplasmic and periplasmic compartments. It binds a variety of glucose-14-glucose polysaccharides, from maltose and lon...
متن کاملMaltose-binding protein as a solubility enhancer.
1. Introduction A major impediment to the production of recombinant proteins in Escheri-chia coli is their tendency to accumulate in the form of insoluble and biologically inactive aggregates known as inclusion bodies. Although it is sometimes possible to convert aggregated material into native, biologically-active protein , this is a time consuming, labor-intensive, costly, and uncertain under...
متن کاملThermodynamics of Unfolding of the All , & Sheet Protein Interleukin - 1 @
The thermal denaturation of interleukin18 in solution has been studied by differential scanning calorimetry at various pH values. I t is shown that the thermal transition of interleukin-18 is completely reversible below pH 2.5, only partly reversible in the pH range 2.5-3.5, and irreversible above pH 3.5. Analysis of the reversible unfolding of interleukin-18 shows that the heat denaturation is...
متن کاملDependence of maltose transport and chemotaxis on the amount of maltose-binding protein.
Maltose-binding protein (MBP) is essential for maltose transport and chemotaxis in Escherichia coli. To perform these functions it must interact with two sets of cytoplasmic membrane proteins, the MalFGK transport complex and the chemotactic signal transducer Tar. MBP is present at high concentrations, on the order of 1 mM, in the periplasm of maltose-induced or malTc constitutive cells. To det...
