1. An isolated polypeptide consisting of the amino acid sequence of SEQ ID NO:1, in which each X in SEQ ID NO:1 is a phenylalanine amino acid. 2. The polypeptide of claim 1, wherein said polypeptide is a purified polypeptide. 3. The polypeptide of claim 1, wherein said polypeptide is a recombinant polypeptide. 4. The polypeptide of claim 3, wherein said polypeptide is a recombinant polypeptide produced in bacteria, yeast, plant, insect, avian, or mammalian cells. 5. The polypeptide of claim 1, wherein said polypeptide is resistant to at least one of oxidation by myeloperoxidase (MPO), oxidation by nitrogen dioxide, oxidation by peroxynitrite (ONOO−), oxidation by peroxycarboxynitrite (ONOOCO2−), or oxidation by a product formed when ONOO− acts in presence of CO2 or HCO3− in buffer. 6. The polypeptide of claim 5, wherein oxidation by myeloperoxidase (MPO) comprises, MPO generated oxidant, oxidation by an MPO-generated reactive chlorinating species, oxidation associated with the MPO/H2O2/Cl− system, oxidation by MPO generated HOCl/OCl−, oxidation by a MPO generated reactive nitrogen species, or oxidation associated with the MPO/H2O2/NO2− system. 7. The polypeptide of claim 1, wherein said polypeptide is resistant to oxidation by MPO. 8. The polypeptide of claim 1, wherein said polypeptide further comprises a polyhistidine-tag. 9. A pharmaceutical composition comprising a polypeptide and a pharmaceutically acceptable excipient, wherein said polypeptide consists of the amino acid sequence of SEQ ID NO:1, in which each X in SEQ ID NO:1 is a phenylalanine amino acid. 10. The pharmaceutical composition of claim 9, wherein the polypeptide is a purified polypeptide. 11. The pharmaceutical composition of claim 9, wherein the composition is formulated for administration to a subject by a route selected from the group consisting of oral administration, nasal administration, rectal administration, intraperitoneal injection, intravascular injection, subcutaneous injection, transcutaneous administration, inhalation administration, and intramuscular injection. 12. The pharmaceutical composition of claim 11, wherein said composition is formulated as a unit dosage formulation. 13. The pharmaceutical composition of claim 11, wherein the pharmaceutical composition is formulated for intravascular administration. 14. The pharmaceutical composition of claim 11, wherein the pharmaceutical composition comprises a powdered form of the polypeptide and a vehicle. 15. The pharmaceutical composition of claim 14, wherein the vehicle comprises sterile pyrogen free water, buffer, or dextrose solution. 16. The pharmaceutical composition of claim 14, wherein the powdered form of the polypeptide comprises lyophilized powdered polypeptide. 17. The pharmaceutical composition of claim 11, wherein the pharmaceutical composition is formulated for subcutaneous injection, transcutaneous administration, or intramuscular injection. 18. The pharmaceutical composition of claim 17, wherein the pharmaceutical composition comprises polymeric, hydrophobic materials, or ion exchange resins.
