The complete nucleotide sequence of the hemagglutinin (HA) gene of the human type B influenza virus B/Singapore/222/79 is presented. Comparison with the only other known sequence of a B hemagglutinin (B/Lee/40) shows that antigenic drift in type B HA genes is essentially the same as already observed within the influenza A H3 subtype, i.e., an accumulation(More)
This paper describes the structural organization of a repetitive DNA sequence isolated from plasmids of Bacillus thuringiensis strain berliner 1715. DNA sequence analysis of this repetitive sequence (RS) revealed all the characteristic features of an insertion sequence (IS). This 1656-bp element is delineated by two 20-bp inverted repeats which are flanked(More)
The selective hydrolysis of the glycosidic bond between the terminal sialic acid and the penultimate sugar has been achieved in the alpha-2-HS-glycoprotein (Fetuin-A) in the presence of H3PW12O40, a Keggin type polyoxometalate. A controlled liberation of sialic acid from the glycoprotein could be achieved at pH 3.0 and 37 °C without the destruction of the(More)
The complete nucleotide sequence of the influenza A/PR/8/34 nucleoprotein gene was determined after cloning for dsDNA copy in pBR322. The nucleoprotein gene is 1517 nucleotides long of which 1446 nucleotides code for 482 amino acids. The calculated amino acid composition is in good agreement with those published for influenza A nucleoprotein genes. The(More)
