The reaction was followed by acquiring 1D NMR experiments at 15-min intervals over 24 h. Gene functions were inferred from BLAST searches followed by gene linkage and cluster analysis. Deletion of yjhC resulted in loss of growth on 2,7-anhydro-Neu5Ac but not on Neu5Ac (Fig. 5C), which could be complemented in trans with yjhC (Fig. 5D), suggesting that the gene encodes an equivalent protein to RgNanOx. To test this hypothesis, the YjhC protein was recombinantly expressed and purified, and its ac...

Which application/end-user or product type may seek incremental growth prospects? AAV6 binding appears to be less affected by neuraminidase compared with AAV1 binding, suggesting that AAV6 may also bind to moieties other than sialic acid on the cell surface. These data suggest that sialic acid present on the cell surface is required for efficient AAV1 and AAV6 transduction. Taken together, these results show that both enzymatic removal and genetic removal of sialic acid on the cell surface redu...

We stained cell lines with lectins that have been used to recognize the following three different epitopes: (i) WGA recognizes all sialic acids, (ii) MAA recognizes α2,3 sialic acid, and (iii) SNA recognizes α2,6 sialic acid. In this report, we demonstrate that AAV1 and AAV6 use both α2,3 and α2,6 N-linked sialic acids for binding and infection. To analyze if the sialylated receptors of AAV1 and AAV6 are glycoproteins or glycolipids, we treated Cos-7 and Pro-5 cells with 200 μg/ml proteinase K....

It was previously believed that influenza pandemics occurred at 10- to 14-year intervals, but it has been over 30 years since H3N2 viruses appeared. Viruses were first remoted in Hong Kong in July 1968. Widespread illness with increased excess mortality was observed in the United States through the winter of 1968-1969. Attack rates were highest (40%) amongst 10- to 14year-old youngsters. In 1918 youngsters would skip rope to the rhyme: I had a bit of chook, Its title was Enza, I opened the wind...

This was followed by the addition of neuraminidase solution or buffer control to each well and continued resistance measurement 4 (or more) h. AAV6 relies more on sialic acid or sialic acid-containing glycoproteins than AAV1 for cell entry and/or subsequent steps of infection. Neuraminidases are enzymes that cleave via hydrolysis α(2-3)-, α(2-6)-, and α(2-8)-linked terminal sialic acid residues bound to Gal, GlcNac, GalNAc, AcNeu, or GlyNeu residues of oligosaccharides, glycolipids, and glycopr...
