Expressed sequence tags (ESTs) that showed significant homology to rat cortistatin (CST) were found in a human fetal brain cDNA library. A protein coded by the cDNA showed 55% identity to rat preprocortistatin in amino acid. Similarly in the generation of mature peptides from rat preprocortistatin, it was expected that cleavage at dibasic amino acids in the(More)
A cDNA clone for the nitrate/nitrite-inducible cytochrome P-450 (P-450) of the fungus Fusarium oxysporum (tentatively termed P-450dNIR) was isolated by an immunoscreening method. Sequence determination revealed a polypeptide of 403 amimo acid residues (Mr = 44,371), which was shown to contain the full-length sequence of the fungal P-450. The amino terminus(More)
The privacy-preserving recommendation system enables us to evaluate the recommended value without leaking the private information of users to service providers. The large overhead in performing cryptographical operations in proportion to the number of users and the number of items is the current issue. In this article, we propose some efficient schemes(More)
The synthesis of xylosyloligosaccharides from beta-(1----4)-xylobiose in the presence of D-mannose by transxylosylation with beta-xylosidase from Aspergillus niger IFO 6662 was studied. At first, the transxylosylation products were separated by charcoal column chromatography in 5% ethanol elution into three peaks, P-1, P-2, and P-3. They were further(More)
