Site-directed mutagenesis techniques are invaluable tools in molecular biology to study the structural and functional properties of a protein. To expedite the time required and simplify methods for mutagenesis, we recommend two protocols in this chapter. The first method for single site-directed mutagenesis, which includes point mutations, insertions, or(More)
Maltose-binding protein (MBP) from Escherichia coli has been shown to be a good substrate for protein engineering leading to altered binding (Marvin and Hellinga, Proc Natl Acad Sci U S A 98:4955-4960, 2001a) and increased affinity (Marvin and Hellinga, Nat Struct Biol 8:795-798, 2001b; Telmer and Shilton, J Biol Chem 278:34555-34567, 2003). It is also used(More)
