Lectins in castor bean seedlings.
The amounts of the two lectins (ricin and Ricinus communis agglutinin) in tissues of castor bean seedlings were followed during germination and early growth. For measurement, lectins in extracts were separately eluted from Sepharose columns; an antibody to the agglutinin was also used to detect the lectins by immunodiffusion. The endosperm of the dry seed contains 3.5 mg total lectin (5.6% of t...
متن کاملOrientation of electron transport activities in the membrane of intact glyoxysomes isolated from castor bean endosperm.
Intact glyoxysomes were isolated from castor bean endosperm on isometric Percoll gradients. The matrix enzyme, malate dehydrogenase, was 80% latent in the intact glyoxysomes. NADH:ferricyanide and NADH:cytochrome c reductase activities were measured in intact and deliberately broken organelles. The latencies of these redox activities were found to be about half the malate dehydrogenase latency....
متن کاملProteases and Peptidases of Castor Bean Endosperm
The endosperm of castor bean seeds (Rkinus comunuis L.) contains two -SH-dependent amptidases, one hydrolyzing L-leucine-,Bnaphthylamide optimally at pH 7.0, and the other hydrolyzing L-proline,B-naphthylamide optimally at pH 7.5. After germination the endosprm contains in addition an -SH-dependent hemoglobin protease, a serinedependent carboxypeptidase, and at least two -SH-dependent enzymes h...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولEvidence that the castor bean allergens are the albumin storage proteins in the protein bodies of castor bean.
The well characterized castor bean (Ricinus communis L.) allergens were identified as the low molecular weight albumin storage proteins in the matrix of the protein bodies in the endosperm. The methods of identification involved molecular weight estimation, amino acid composition, stability at 100 degrees C, solubility in various solvents, gel electrophoresis, and immunological techniques. The ...
