the composition of the cell wall of fusicoccum amygdali.	1. the cell wall of fusicoccum amygdali consisted of polysaccharides (85%), protein (4-6%), lipid (5%) and phosphorus (0.1%). 2. the main carbohydrate constituent was d-glucose; smaller amounts of d-glucosamine, d-galactose, d-mannose, l-rhamnose, xylose and arabinose were also identified, and 16 common amino acids were detected. 3. chitin, which accounted for most of the cell-wall glucosamine, was isolated in an undegraded form by an enzymic method. chitosan was not detected, but traces of gluc ...	1971	5144751
bilirubin glucuronyltransferase. specific assay and kinetic studies.	1. bilirubin glucuronide was synthesized in vitro in a system containing a rat liver microsomal fraction, udp-glucuronic acid, mg(2+) and bilirubin. the enzymic synthesis was accomplished without the addition of a bilirubin carrier. 2. azobilirubin and azobilirubin glucuronide were separated by t.l.c. and paper chromatography and the measurement of the conjugate provided a specific assay for bilirubin udp-glucuronyltransferase (ec 2.4.1.17). 3. this diazo compound was labelled when [u-(14)c]udp- ...	1971	5158913

purification and characterization of a blood-group a reactive hemagglutinin from the snail helix pomatia and a study of its combining site.		1969	4241272
the structure of a glycopeptide isolated from the yeast cell wall.	1. glycopeptides containing mannose were extracted from isolated yeast cell walls by ethylenediamine and purified by treatment with pronase and fractionation on a sephadex column. 2. a glycopeptide that appeared homogeneous on electrophoresis and ultracentrifugation had a molecular weight of 76000, and contained a high-molecular-weight mannan and approx. 4% of amino acids. 3. the amino acid composition of the peptide was determined. it was rich in serine and threonine and also contained glucosam ...	1968	5685868
studies on glycoproteins. xv. substrate-dependence of o-seryl-n-acetylgalactosaminide glycosidase (helix pomatia) activity and mechanism of the enzymatic reaction.		1967	6077032
the hydrolysis of glycosyl fluorides by glycosidases.	1. alpha-d- and beta-d-glucopyranosyl, alpha-d- and beta-d-galactopyranosyl, alpha-d-mannopyranosyl and alpha-d-xylopyranosyl fluorides were hydrolysed specifically by the respective glycosidases from several sources. 2. use of specific inhibitors with a mixture of glycosidases from helix pomatia intestinal juice showed that each glycosyl fluoride was hydrolysed only by the respective glycosidase. alpha-d-glucopyranosidase and alpha-d-xylopyranosidase activities were shown to be due to different ...	1967	5584010

protoplast formation and yeast cell-wall structure. the action of the enzymes of the snail, helix pomatia.	1. the digestive juice of the snail helix pomatia was used in the study of the degradation of isolated cell-wall preparations from a strain of saccharomyces carlsbergensis. 2. the crude enzyme system was fractionated by gel filtration and the activities of the more specific fractions thus obtained were examined. 3. results are discussed with respect to (a) the nature of various factors that are essential for protoplast formation and cell-wall dissolution and (b) structures envisaged in yeast cel ...	1966	5964965
urinary excretion of c-20-reduction products of corticosterone.	1. a 200 mg. portion of corticosterone was ingested by a healthy man and the urine collected. part of the urine was treated with the gastric juice of helix pomatia and extracted with ethyl acetate, and the extract fractionated with girard t. paper-chromatographic separation of the non-ketonic fraction in the bush (1952) system b(5) revealed the presence of two unknown polar components. 2. the unknown compounds did not possess a reducing (blue tetrazolium) or a reducible (potassium borohydride) g ...	1965	14342242

some cytological and pathogenic properties of spheroplasts of candida albicans.	kobayashi, george s. (tulane university, new orleans, la.), lorraine friedman, and judith f. kofroth. some cytological and pathogenic properties of spheroplasts of candida albicans. j. bacteriol. 88:795-801. 1964.-spheroplasts of candida albicans were prepared by use of an enzymatic mixture from the digestive tract of the snail helix pomatia. untreated cells exhibited well-defined cell walls, whereas such structures were absent from spheroplasts. the intravenous inoculation of either spheroplast ...	1964	14208520
