By Sephadex G-50 gel filtration, Resource Q anionic exchange and C4 reversed phase liquid high performance liquid chromatography, a proteinase inhibitor protein (Ranaserpin) was identified and purified from the eggs of the odour frog, Rana grahami. The protein displayed a single band adjacent to the molecular weight marker of 14.4 kDa analyzed by SDS-PAGE. The inhibitor protein homogeneity and its...
A bradykinin-like peptide has been isolated from skin secretions of rufous-spotted torrent frog, Amolops loloensis. This bradykinin-like peptide was named amolopkinin. Its primary structure, RAPVPPGFTPFR, was determined by Edman degradation and mass spectrometry. It is structurally related to bradykinin-like peptides identified from skin secretions of other amphibians. Amolopkinin is composed of 12...
