Abstract: The hydroxyapatite elution behavior of 3 fragments of human XPA (M98-F219 = XPA-MBD M59-F219 = XPA-EM M59-M273 = XPA-deltaN58) and full-length human XPA containing a 6-residue, N-terminal histidine tag (h6-XPA) are described. With increasing concentration of potassium phosphate the proteins elute in the order: XPA-EM, XPA-MBD, XPA-deltaN58, and h6-XPA. If hydroxyapatite affinity is related to DNA-binding affinity, then h6-XPA and XPA-deltaN58 may bind DNA more tightly than XPA-MBD and XPA-EM.
