Subunit Structure of Helix pomatia A Hemagglutinin

Scandinavian Journal of Immunology, 1972
Equilibrium centrifugation shows that the hemagglutinin has a mol. wt. of 79, 000 ± 4, 000. It contains approximately 18 moles of half cysteine, all as disulfide bonds. Unfolding agents alone (7 M guanidine.HCl) dissociate the hemagglutinin into a subunit of mol. wt. 26, 000–30, 000.

The isolectins of Helix pomatia

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1979
Helix pomatia lectin was fractionated into several (at least 12) components by isolectric focusing in PharmalyteTM. Eight of these were recovered from a preparative column experiment and shown to be essentially pure by analytical electrofocusing in polyacrylamide gel slabs.

β-d-mannosidase from Helix pomatia

Carbohydrate Research, 1983
beta-D-Mannosidase (beta-D-mannoside mannohydrolase EC 3.2.1.25) was purified 160-fold from crude gut-solution of Helix pomatia by three chromatographic steps and then gave a single protein band (mol. wt. 94,000) on SDS-gel electrophoresis, and three protein bands (of almost identical isoelectric points) on thin-layer isoelectric focusing.

Ultrastructure of galactogen in the albumen gland of Helix pomatia

Journal of Ultrastructure Research, 1969
The gastropod albumen gland produces a secretion containing galactogen, a galactose polysaccharide. The albumen gland of Helix pomatia is a compound tubular organ composed of centrotubular cells and secretory cells that form large PAS-positive globules. The formation and content of these globules were studied with the electron microscope.

Identification of agglutinin receptors on hemocytes of Helix pomatia

Journal of Invertebrate Pathology, 1977
Abstract The attachment of opsonized foreign particles to phagocytic cells indicates the occurrence of opsonin receptors on the surfaces of the phagocytes. There is good evidence that naturally occurring hemagglutinins may serve as opsonins in invertebrates.

Enzymatic synthesis of galactogen in the snall, Helix, pomatia

Biochemical and Biophysical Research Communications, 1965
Abstract The galactose polymer, galactogen, has been reported in numerous pulmonate snails ( Ghose, 1963 ; Horstmann, 1956 ; May, 1931 ; McMahon et , al. , 1957 ; Meenakshi, 1954 ; Rigby, 1963 ). Whereas this polysaccharide is found exclusively in the reproductive system (albumen gland) and freshly laid eggs, glycogen is present in the

Circulatory pressures in Helix pomatia L.

Comparative Biochemistry and Physiology Part A: Physiology, 1971
Abstract 1. 1. Measurements have been made of the pressures generated by the heart of Helix . 2. 2. The heart produces a gradient of some 19 cm of water between the pulmonary vein and the aorta. Diastolic pressure in the auricle is about 5 cm and systolic pressure in the ventricle is about 24 cm. 3. 3.

Buffers in the blood of the snail,helix pomatia L.

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. Blood from the haemocoels of active snails had an average pH of 7·76. In aestivating snails, it tended to contain less bicarbonate to have a higher pCO2, so being more acid (mean: pH 7·51). 2. 2. Blood from the heart was 0·12 pH units more alkaline. 3. 3. The pH of maximum buffering by haemocyanin is lowered in the presence
