Isolation of a starfish myorelaxant peptide (SMP) isotype from the pyloric caeca of Patiria pectinifera

Isolation and characteristics of trypsin from pyloric ceca of the starfish Asterina pectinifera.

Trypsin was purified from pyloric ceca of the starfish Asterina Pectinifera by ammonium sulfate precipitation, gel filtration, and cation-exchange chromatography. Final enzyme preparation was nearly homogeneous in sodium dodecyl sulfate-polyacrylamide gel electrophoresis and its molecular weight was estimated as approximately 28000. Optimum pH and temperature of A. pectinifera trypsin for hydro...

Isolation and characteristics of phospholipase A2 from the pyloric ceca of the starfish Asterina pectinifera

Identification of a novel starfish neuropeptide that acts as a muscle relaxant

Neuropeptides that act as muscle relaxants have been identified in chordates and protostomian invertebrates but little is known about the molecular identity of neuropeptides that act as muscle relaxants in deuterostomian invertebrates (e.g. echinoderms) that are 'evolutionary intermediates' of chordates and protostomes. Here, we have used the apical muscle of the starfish Patiria pectinifera to...

L-proline Transport Systems of Starfish Pyloric Caeca

Purified brush-border membrane vesicles (BBMV) of starfish [Pycnopodia helianthoides (Brandt)] pyloric caecal epithelium were prepared by magnesium precipitation in order to characterize the possible role of this organ in amino acid transport. L-[H]proline uptake by these vesicles was Na-dependent and greater at pH7.5 than at pH5.5. L-Pipecolate was a competitive inhibitor of L-proline influx i...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
