Factor Xa cleaves after the arginine residue in its preferred cleavage site Ile-Glu/Asp-Gly-Arg. It will sometimes cleave at other basic residues, depending on the conformation of the protein substrate. The most common secondary site, among those that have been sequenced, is Gly-Arg.

  • Compatible for use with the pMAL™ Protein Fusion and Purification System (NEB #E8200)
  • Allows for convenient removal of MBP by loading the MBP-fusion digest onto amylose resin and collecting your protein of interest in the flow through

Factor Xa cleaves after the arginine residue in its preferred cleavage site Ile-(Glu or Asp)-Gly-Arg. It will sometimes cleave at other basic residues, depending on the conformation of the protein substrate (1,2,3). The most common secondary site, among those that have been sequenced, is Gly-Arg. There seems to be a correlation between proteins that are unstable in E.coli and those that are cleaved by Factor Xa at secondary sites; this may indicate that these proteins are in a partially unfolded state (Walker, I., Riggs, P., unpublished observations). Factor Xa will not cleave a site followed by proline or arginine.
