Specific adenosine phosphorylase from hepatopancreas of gastropod Helix pomatia

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993
1. Specific adenosine phosphorylase from Helix pomatia hepatopancreas was separated from inosine-guanosine phosphorylase and purified 100-165 times; molecular weights were found to be 71,000 and 90,000, respectively. 2. The enzyme is specific for deoxy- and adenosine; it is inactive for 5'-methylthioadenosine and 5-amino-4-imidazole-carboxyamide ...

Immunofluorescent evidence of an FMREamide-like peptide in the peripheral nervous system of the gastropod mollusc Helix aspersa

Neuroscience Letters, 1983
An antiserum raised against the FMRFamide peptide revealed a highly developed peripheral nervous system in the mollusc Helix aspersa. Immunoreactive fibres associated with muscular fibres are observed in all organs. Cell bodies are frequently seen, for example in the digestive and genital tracts.

Involvement of glycans in the immunological cross-reaction between α-macroglobulin and hemocyanin of the gastropod Helix pomatia

Biochimie, 2009
By tandem-crossed immunoelectrophoresis and ELISA experiments an immunological relationship was observed between alpha-macroglobulin (alphaM) and hemocyanin (Hc) of the terrestrial snail Helix pomatia. Both glycoproteins occur in the hemolymph: alphaM (minor component) as a specific proteinase inhibitor, Hc (consisting of three components: alpha(D)-HpH,

Localization and quantification of Cd- and Cu-specific metallothionein isoform mRNA in cells and organs of the terrestrial gastropod Helix pomatia

Toxicology and Applied Pharmacology, 2003
A quantitative assay based on real-time detection polymerase chain reaction (rtdPCR) was applied to analyze basal and metal-induced mRNA levels of two metallothionein (MT) isoforms (Cd-MT and Cu-MT) in organs of the terrestrial gastropod Helix pomatia.

Structure and in vitro cytocompatibility of the gastropod shell of Helix pomatia

Tissue and Cell, 2006
Distinguishing features of biological constructions are high stability and adaptation to their environment. Beside biocompatibility, nontoxicity and degradability these characteristics are demanded for new biomaterials in the field of tissue engineering. This study investigated the chemical composition, the organization and the in vitro osteoconductive

Isoform‐specific quantification of metallothionein in the terrestrial gastropod Helix pomatia I. molecular, biochemical, and methodical background

Environmental Toxicology and Chemistry, 2004
Abstract The biomarker concept is an important approach of modern ecotoxicology based on the detection and quantification of molecular, biochemical, cellular, or physiological alterations in organisms as the result of exposure to toxic compounds.

Distribution of Gaba and Other Amino Acids In Different Tissues of The Gastropod Mollusc Helix Pomatia, Including In Vitro Experiments With^,4c Glucose and^I4c Glutamic Acid

International Journal of Neuroscience, 1971
Microchromatography on 3 × 3 cm polyamide layers of dansyl-compounds was used to study the distribution of free amino acids, GABA, serotonin, 5-hydroxyindole and 5-hydroxytryptophan in the brain, optic tentacle, pharyngeal retractor muscle and heart of ...

Aromatic alcohol oxidase and aldehyde oxidase activities in the digestive gland of three species of terrestrial gastropod (Helix aspersa, arion ater, limax flavus)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993
1. Digestive gland homogenates of three species of terrestrial gastropod mollusc were used to prepare sources of soluble aldehyde oxidase and solubilized aromatic alcohol oxidase activities. 2. The snail (Helix aspersa) had two aldox isoenzymes each able to utilize salicylaldehyde whereas two slug species had a single apparent activity inhibitable by ...

Possible use of terrestrial gastropod (Helix aspersa aspersa) and its life stages as a tool for environmental risk assessment

Chemistry and Ecology, 2022
This paper presents a laboratory study using terrestrial gastropods. Two different life stages of a cosmopolitan terrestrial gastropod Helix aspersa aspersa (syn. Cantareus aspersus or Cornu aspersum) were used.

Isolation and characterization of an α-macroglobulin from the gastropod mollusc Helix pomatia with tetrameric structure and preserved activity after methylamine treatment 1Enzymes: chymotrypsin (EC 3.4.21.1), elastase (EC 3.4.21.36), N-glycosidase F (EC 3.2.2.18), thermolysin (EC 3.4.24.4), trypsin (EC 3.4.21.4). 1

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 2001
A proteinase inhibitor with M(r) 697000 and 20.3% (w/w) carbohydrate was isolated from the haemolymph of the snail Helix pomatia and characterized. It was shown to have a tetrameric structure with subunits disulphide linked by two. It inhibited the activity of several types of proteinases against large substrates but not that of trypsin against N-alpha-
