The use of subtype-selective voltage-sensitive calcium channel (VSCC) antagonists has established that neurotransmitter release in mammalian brain is mediated by N-like and P-like VSCCs, and that other subtypes also contribute significantly. To determine the roles presynaptic VSCCs play in nervous system function and to evaluate the therapeutic potential of(More)
Synthetic versions of seven naturally occurring omega-conopeptides were subjected to structural analyses in order to determine their disulfide bridge pattern. The method applied in this study uses a combination of amino-acid composition and peptide sequence analysis of various peptide fragments generated by different enzymatic digestions. A temperature(More)
A novel selective calcium channel antagonist peptide, SNX-325, has been isolated from the venom of the spider Segestria florentina. The peptide was isolated using as bioassays the displacement of radioiodinated omega-conopeptide SNX-230 (MVIIC) from rat brain synaptosomal membranes, as well as the inhibition of the barium current through cloned expressed(More)
An extracellular protease was purified from Pseudomonas thermaerum GW1 a new strain identified by morphological, biochemical and 16S rDNA sequencing. It was isolated from soil of Poultry waste site at Ghazipur near Ghaziabad, Delhi. The strain produces extra cellular protease in the culture media that was maintained at 37°C, 140 rpm. The media was harvested(More)
A trypsin-chymotrypsin inhibitor was isolated from the seeds of amaranth--a highly nutritious protein source. The purification of the inhibitor (AmI) was carried out by affinity chromatography on trypsin-Sepharose and by HPLC. AmI is a single-chain protein of 8 kD, as determined by electrophoresis on SDS-polyacrylamide gels and by gel exclusion on Sephadex(More)
Phytase is an enzyme which catalyzes the total hydrolysis of phytate to less phosphorylated myo-inositol derivatives and inorganic phosphate and digests the undigestable phytate part present in seeds and grains and therefore provides digestible phosphorus, calcium and other mineral nutrients. Phytases are frequently added to the feed of monogastric animals(More)
Venoms of the predatory cone snails Conus textile, Conus striatus, and Conus magus were subjected to comprehensive analysis of peptide content. With the fish-eating cone snails C. magus and C. striatus, the most abundant venom peptides were of > 30-50 residues, whereas the predominant peptides in the venom of the mollusc-eating snail, C. textile, were of(More)
Phytase is an enzyme that is found extensively in the plant kingdom and in some species of bacteria and fungi. This paper identifies and analyses the available full length sequences of β-propeller phytases (BPP). BPP was chosen due to its potential applicability in the field of aquaculture. The sequences were obtained from the Uniprot database and subject(More)
