Purification, characterization and comparison of reptile lysozymes.
Cation exchange column chromatography and gel filtration chromatography were used to purify four reptile lysozymes from egg white: SSTL A and SSTL B from soft shelled turtle (Trionyx sinensis), ASTL from Asiatic soft shelled turtle (Amyda cartilagenea) and GSTL from green sea turtle (Chelonia mydas). The molecular masses of the purified reptile lysozymes were estimated to be 14 kDa by SDS-PAGE....
متن کاملTick lysozymes
Ticks are blood feeding arthropod parasites transmitting a wide variety of pathogens to their vertebrate hosts. The vector capability of ticks is tightly linked to their immune system. Ticks can defend themselves against microbial infection with a variety of antimicrobial peptides comprising lysozymes, defensins, and unique molecules not found in other arthropods. Lysozymes are hydrolytic enzym...
متن کاملMolecular and immunological characterization of shellfish allergens.
Shellfish (crustaceans and mollusks) have long been known as a common cause of allergic reactions to food. Like other food allergies, the allergic reactions to shellfish involve IgE-mediated Type I hypersensitivity. Biochemical and molecular studies have documented the major shrimp allergen is the muscle protein tropomyosin. Subsequent molecular cloning studies on lobsters and crabs have charac...
متن کاملLysozymes in molluscs
Invertebrates lack antibody-mediated humoral immune systems; however, they are believed to possess efficient host defense mechanisms involving humoral defense molecules that are similar in function to antibodies. Lysozymes are a group of enzymes that cleave the glycosidic bonds between N-acetylmuramic acid and N-acetylglucosamine (two amino sugars) in the peptidoglycans that form bacterial cell...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
