Vipera lebetina venom contains different metallo- and serine proteinases that affect coagulation and fibrin(ogen)olysis. A novel serine proteinase from V. Lebetina venom having ChymoTrypsin Like Proteolytic activity (VLCTLP) was purified to homogeneity from the venom using Sephadex G-100sf, DEAE-cellulose, heparin–agarose and FPLC on Superdex 75 chromatographies. VLCTLP is a glycosylated serine proteinase...
Two novel highly homologous defensins, Sm-AMP-D1 and Sm-AMP-D2, were isolated from seeds of common chickweed Stellaria media L. (family Cariophyllaceae). They show sequence homology to defensins of the Brassicaceae plants and display strong inhibitory activity against phytopathogenic fungi and oomycetes in the micromolar range (IC 50 ≤1μM). The cDNA sequences coding for Sm-AMP-D1 and Sm-AMP-D2...
Herbivorous marine gastropods such as abalone and sea hare ingest brown algae as a major diet and degrade the dietary alginate with alginate lyase (EC 4.2.2.3) in their digestive fluid. To date alginate lyases from Haliotidae species such as abalone have been well characterized and the primary structure analyses have classified abalone enzymes into polysaccharide-lyase-family 14 (PL-14). However,...
