TRYPTOPHAN AS A FUNCTIONAL REPLACEMENT FOR ADP-RIBOSE-ARGININE IN RECOMBINANT PROTEINS |
摘要 |
A method is disclosed for producing a polypeptide with a modified activity o r stability, by replacing an arginine residue capable of being ADP-ribosylated with a tryptophan or a phenylalanine. In one embodiment, compositions are provided that include polypeptides, such as alpha defensin, with arginine-to - tryptophan or arginine-to-phenylalanine substitutions, where the arginine residue is capable of being ADP-ribosylated. In another embodiment, methods are disclosed for modifying an immune response in a subject. |
