摘要:
A novel family of proteins has been identified. The proteins are derived from allergenic pollens and exhibit serine-proteinase-like activity. The proteins have a molecular weight of about 85-95 kD as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis; and a molecular weight of about 67 kD as determined by Fast Protein Liquid Chromatography. The proteins are resistant to inhibition by α-2-macroglobulin, α-1-proteinase inhibitor, trypsin inhibitors and are sensitive to inhibition by phenyl methane sulfonyl fluoride, difluorophenol, benzamidine, antipain, leupeptin and tosyl-L-lysine chloromethyl ketone.
摘要:
Provided herein is a nucleotide sequence encoding an Arg-specific gingipain named gingipain-1 isolated from Porphyromonas gingivallis, having an apparent molecular mass of 50 kDa as estimated by SDS gel electrophoresis and an apparent molecular mass of 44 kDa as estimated by gel filtration chromatography. Gingipain-1 has amidolytic and proteolytic activity for cleavage after arginine residues and has no amidolytic and/or proteolytic activity for cleavage after lysine residues. Its activity is inhibited cysteine protease group-specific inhibitors and chelating agents. It is stabilized by Calcium and stimulated by glycine-containing peptides and glycine analogues.

摘要:
The present invention is directed to methods of obtaining plant-derived delipidated extracts that inhibit apoptosis, the extracts obtained, compositions containing said extracts and methods of using said compositions. The figure is a bar graph which illustrates a lower incidence of diarrhea in rats treated with methotrexate and fed a diet of compositions of the claimed invention as compared to controls.
