hemocyanins in spiders, xviii. complete amino-acid sequence of subunit e from eurypelma californicum hemocyanin.	the complete amino-acid sequence of subunit e of the hemocyanin from the tarantula, eurypelma californicum, was determined by a combination of manual and automated methods. by limited proteolysis with chymotrypsin, two large fragments (e-chn 29 and e-chn 42) were obtained. the large peptides were further cleaved with cyanogen bromide, trypsin (with and without prior blocking of lysine residues), chymotrypsin, staphylococcus aureus proteinase, astacus fluviatilis proteinase, or 25% formic acid. t ...	1983	6357986
amino acid sequence of crayfish (astacus fluviatilis) trypsin if.	the complete amino acid sequence of trypsin from the crayfish astacus fluviatilis has been determined. the protein was fragmented with cyanogen bromide after s-carboxymethylation of the reduced disulfide bonds and by trypsin after s-carboxymethylation as well as after succinylation of lysine residues and aminoethylation of the reduced disulfide bonds. peptides were purified by gel filtration and by reversed-phase high-performance liquid chromatography. stepwise degradation was performed in a spi ...	1983	6838862
induction of degranulation and lysis of haemocytes in the freshwater crayfish, astacus astacus by components of the prophenoloxidase activating system in vitro.	to study the role of the prophenoloxidase activating system, an enzyme cascade located in the haemocytes of crustaceans, in the cellular defences of the freshwater crayfish, astacus astacus in vitro, monolayer cultures of mixed or separated haemocyte populations, isolated by density gradient centrifugation, were challenged with the bacterium, moraxella sp. pre-coated with phenoloxidase and the other attaching proteins in crayfish haemocyte lysate (hls), or in the case of controls, with saline or ...	1983	6413069
udpglucosyltransferase and its kinetic fluorimetric assay.	a rapid, kinetic assay for udpglucosyltransferase has been developed using 1-naphthol as substrate. it is based on the continuous fluorimetric monitoring of 1-naphthyl glucoside formation during the reaction at physiological ph. the conjugate is easily distinguished from aglycone, since their fluorimetric properties differ. glucoside biosynthesis in vitro by microsomal preparations isolated from the gut and fat body of cockroaches periplaneta americana and leucophaea maderae, and from the green ...	1983	6218988
[ultrastructural organization of the gastric ganglion in the crayfish].	anatomy of the gastric ganglion in the stomatogastric region of the vegetative nerve system has been studied in astacus astacus at light optic and ultrastructural levels. topography, neuroglial and interneuronal relationships of its elements have been described. various types of synapses of the ganglionic neuropil have been described. the role of the ganglionic structural elements in receiving and treating sensory information and in regulation of gastric movements is discussed.	1980	7458692

ultrastructure of the y-organ of astacus astacus (l.) (crustacea) in relation to the moult cycle.	the electron microscopical investigation of y-organs of astacus astacus revealed that during intermoult (stage c) the cytoplasm is poorly developed and that it increases at premoult (stage d). it then shows the typical signs of steroid production, namely agranular endoplasmic reticulum and mitochondria of the tubular type. furthermore, a larger type of mitochondria with a regular pattern of internal structure is described.	1979	455392
crayfish carboxypeptidase. affinity chromatography, characterization and amino-terminal sequence.	in an effort to trace the evolutionary history of the pancreatic metalloexopeptidases, carboxypeptidase has been isolated from the cardia of the crayfish astacus fluviatilis. the isolation procedure included affinity chromatography on a column of potato carboxypeptidase inhibitor covalently linked to sepharose. approximately 25 mg of pure enzyme can be obtained by the present procedure from 50 ml of cardia fluid. the pure enzyme resembles bovine carboxypeptidase b in specificity and is inhibited ...	1979	436840
[a new method of therapy for branchiobdellosis in crayfish].	crayfish (astacus fluviatilis fabricius, 1793) were treated three times with a bath of diluted ammonia water and proflavine for four and six minutes at a temperature of 18 degrees c to get rid of the ectoparasitic worms of branchiobdella parasita henle, 1835; the hatching ability of the branchiobdella parasita eggs was stopped after the treatment. no lethal effect of the bath on the crayfish of 5 to 14 cm was observed, the lethal effect on the young crayfish borne on the uropods of the female cr ...	1979	106505

[fatty acid composition of phospholipids from rabbit and crayfish skeletal muscle sarcolemma and sarcoplasmic reticulum membranes].	a comparative analysis of fatty acid composition of lipid components from skeletal muscle sarcolemma and sarcoplasmic reticulum membranes of rabbits and crayfishes astacus fluviatilis and a. leptodactylus has been made by means of gas-liquid chromatography of methyl esters of fatty acids. there are slight differences between external and internal membranes in fatty acids composition of lipids in the same animal. considerable differences were found, however, when lipids in corresponding membranes ...	1975	1217298
