| primary structural analysis of sulfhydryl protease inhibitors from pineapple stem. | pineapple stem acetone powder provides a rich source of the sulfhydryl protease bromelain and of a family of compositionally similar but chromatographically distinct polypeptide inihibtors of this enzyme. the isoinhibitors have molecular weights of 5600, and they contain five disulfide bonds and about 50 amino acids each (perlstein, s. h., and kezdy, f.j. (1973) j. supramol. struct. 1, 249-254). primary structural analysis of one of the seven inhibitor fractions (vii) revealed extensive microhet ... | 1975 | 1112827 |
| photosensitized inactivation of stem bromelain. oxidation of histidine, methionine, and tryptophan residues. | pineapple stem bromelain was photooxidized in the presence of methylene blue used as a sensitizer. the essential sulfhydryl group of the enzyme protein rapidly became inaccessible to react with 5,5'-dithiobis(nitrobenzoic acid), but the reactivity was readily regained to the original level upon treatment with dithiothreitol. even after such reduction, the photooxidized enzyme showed a markedly decreased hydrolytic activity on casein. spectral examination revealed that the oxidized enzyme had tyr ... | 1975 | 1120100 |
| mirex residues in wildlife and soils, hawaiian pineapple-growing areas--1972-74. | a monitoring program was conducted in the pineapple-growing areas of hawaii from 1972 to 1974 to survey mirex residues in sediments, soils, and aquatic and terrestrial wildlife. residues in pineapple field soils ranged from 3 to 18 ppb 9 months after mirex had been applied. no residues were found in the sediments. only 8 fish of 110 aquatic animals sampled contained mirex; these levels were low and ranged from 3 to 7 ppb. mirex residues in birds ranged from undetectable to 10 ppm; residues in ro ... | 1975 | 1221351 |
| purification and characterization of a proteinase from pineapple fruit, fruit bromelain fa2. | fruit bromelain fa2, the main proteinase component of the juice of pineapple fruit, has been purified and characterized. 1. efficient extraction of this enzyme from the crude material was possible using "cellulosin ap," a microbial polysaccharidase preparation containing cellulase, hemicellulase, and pectinase. the enzyme was purified mainly by successive applications of anion-exchange chromatography, yielding an apparently homogeneous protein as judged by several physical, chemical, and immunoc ... | 1976 | 956152 |
| studies on the hydrazinolysis of glycoproteins. core structures of oligosaccharides obtained from porcine thyroglobulin and pineapple stem bromelain. | hydrazinolysis of porcine thyroglobulin glycopeptides and of pineapple stem bromelain [ec 3.4.22.4] permitted the isolation of almost intact carbohydrate chains of these glycoproteins. on the basis of permethylation analyses of the released oligosaccharides after reduction with nabh4, the core structures of unit a-type and unit b-type carbohydrate chains of porcine thyroglobulin were deduced to be manalpha1 leads to 6[manalpha1 leads to 3]manbeta1 leads to 4glcnacbeta1 leads to 4[ralpha1 leads t ... | 1976 | 1035216 |

| characterization of phosphoenolpyruvate carboxykinase from pineapple leaves ananas comosus (l.) merr. | phosphoenolpyruvate carboxykinase has been partially purified from pineapple (ananas comosus [l.]) leaves. specific activities obtained show it to be a major activity in this tissue. above 15 c, the respective activation energies for decarboxylation and carboxylation are 13 and 12 kcal/mol. below 15 c, there are discontinuities in arrhenius plots with an associated large increase in activation energy. the adenine nucleotides are preferred to other nucleotides as substrates. the apparent km value ... | 1977 | 16659905 |
| carbon dioxide exchange and acidity levels in detached pineapple, ananas comosus (l.), merr., leaves during the day at various temperatures, oxygen and carbon dioxide concentrations. | the effects of temperature, o(2), and co(2) on titratable acid content and on co(2) exchange were measured in detached pineapple (ananas comosus) leaves during the daily 15-hour light period. comparative measurements were made in air and in co(2)-free air. increasing the leaf temperature from 20 to 35 c decreased the total co(2) uptake in air and slightly increased the total co(2) released into co(2)-free air. between 25 and 35 c, the activation energy for daily acid loss was near 12 kcal mol(-1 ... | 1977 | 16659832 |

| allergic reactions, including asthma, to the pineapple protease bromelain following occupational exposure. | a 58-year-old pharmaceutical worker regularly developed asthma and rhinitis when handling bromelain, a purified protease of pineapple (ananas comosus), at her work-place, where she had been employed for about 10 years. rast and prick test showed strong positive reactions to bromelain. both inhalation test with 0.03 mg bromelain and peroral challenge by ingestion of 190 g pineapple resulted in asthmatic reactions; the latter challenge was accompanied by gastrointestinal symptoms. five of six work ... | 1979 | 498486 |
| aflatoxigenic potential of dried figs, apricots, pineapples, and raisins. | spores from 3 aflatoxigenic strains were applied to the surface of dried figs, pineapple slices, apricots, and raisins. half of the samples of each foodstuff was autoclaved (cooked) before inoculation. all 3 strains produced some toxin but not in all of the foodstuffs. no aflatoxins were found in any of the raisin cultures. the overall potential for toxin production in the dried fruit was apricot greater than fig greater than pineapple greater than raisin. among the cooked substrates, the order ... | 1979 | 500544 |
| hydrolytic enzymes in the central vacuole of plant cells. | the hydrolase content of vacuoles isolated from protoplasts of suspension-cultured tobacco cells, of tulip petals, and of pineapple leaves, and the sedimentation behavior of tobacco tonoplasts were studied. three precautions were found to be important for the analysis of vacuolar hydrolases and of the tonoplast. (a) purification of protoplasts in a ficoll gradient was necessary to remove cell debris which contained contaminating hydrolases adsorbed from the fungal cell-wall-degrading enzyme prep ... | 1979 | 16660869 |
| relationships between stomatal behavior and internal carbon dioxide concentration in crassulacean acid metabolism plants. | measurements of internal gas phase co(2) concentration, stomatal resistance, and acid content were made in crassulacean acid metabolism plants growing under natural conditions. high co(2) concentrations, sometimes in excess of 2%, were observed during the day in a range of taxonomically widely separated plants (opuntia ficus-indica l., opuntia basilaris engelm. and bigel., agave desertii engelm., yucca schidigera roezl. ex ortiges, ananas comosus [l.] merr., aloe vera l., cattleya sp. and phalan ... | 1979 | 16660851 |
| the rapid isolation of vacuoles from leaves of crassulacean acid metabolism plants. | a technique is presented for the isolation of vacuoles from sedum telephium l. leaves. leaf material is digested enzymically to produce protoplasts rapidly which are partially lysed by gentle osmotic shock and the inclusion of 5 millimolar ethyleneglycol-bis (beta-aminoethyl ether)n,n'-tetraacetic acid in the wash medium. vacuoles are isolated from the partially lysed protoplasts by brief centrifugation on a three-step ficoll-400 gradient consisting of 5, 10, and 15% (w/v) ficoll-400. a majority ... | 1980 | 16661440 |
| nutritional requirements and biochemical activities of pineapple pink disease bacterial strains from hawaii. | bacteria which cause pink disease of pineapple, identified on the basis of their nutritional and biochemical activities, were found to belong to three genera. these bacteria include the following species: gluconobacter oxydans, acetobacter aceti, and erwinia herbicola. several pink disease strains required one to three vitamins for growth. both g. oxydans strains 303d and 180 required biotin, nicotinic acid, and pantothenic acid for growth; e. herbicola 189 required only nicotinic acid; however, ... | 1980 | 7436404 |
| fibrinolytic and antithrombotic action of bromelain may eliminate thrombosis in heart patients. | it has been established that a bromelain plasminogen activator will produce plasmin in rat experiments. in addition the plasmin cleaves hageman factor in a way that leads to a strong release of kallikrein but a weak release of thrombin. a possible mechanism is suggested to explain how the body can maintain thrombin at a level too low to cause platelet aggregation but adequate to stimulate release of prostaglandins and enzymes for more than 24 hours from a single dose of the pineapple enzymes. si ... | 1980 | 6256612 |
