The ovary of the desert locust, Schistocerca gregaria, contains multiple inhibitors of serine proteases. Five serine protease inhibitors, designated SGPI-1-5 (Schistocerca gregaria protease inhibitors) were purified from methanolic extracts of mature ovaries and analyzed by mass spectrometry and amino acid sequencing. The revealed primary structures display amino acid similarities and are related to the serine protease inhibitors identified in the hemolymph of Locusta migratoria. All inhibitors… CONTINUE READING
