Influenza virus neuraminidase.
Antiserum specific for influenza A2 neuraminidase was produced by immunization of rabbits with the purified enzyme which had been isolated by electrophoresis from the proteins of a detergent-disrupted AoA2 influenza virus recombinant [X-7 (Fl)]. This recombinant contained hemagglutinin of the Ao subtype and A2 neuraminidase. Antiserum to the isolated A2 neuraminidase did not react in any of fou...
متن کاملThe exoceliular , B - lactamase of Streptomyces albus G
The exoceilular f-lactamase of Streptomyces albus G has been purified to near protein homogeneity. It consists of one single polypeptide chain of mol.wt. 30000-31000, has a rather low isoelectric point (at pH 6.0) and contains less lysine (2.1%) and more half-cystine residues than most fi-lactamases from other Gram-positive bacteria. Penicillins are much better substrates than A3-cephalosporins...
متن کاملDifferential release of sialic acid from normal and malignant cells by Vibrio cholerae neuraminidase or influenza virus neuraminidase.
A comparison was made between the amounts of sialic acid released from viable cell suspensions of normal and malignant cells by Vibrio cholerae neuraminidase (VCN) and by influenza virus neuraminidase. More sialic acid can be removed by enzyme digestion from various tumors than from normal lymphoid cells. More sialic acid can be removed from the surface of both normal and tumor cells by VCN tha...
متن کاملBaculoviral Expression of Influenza A Virus (H1N1 New Caledonia) Neuraminidase in Insect Cells
Background and Aims: Each year, the influenza virus causes moderate to severe infections with a high prevalence throughout the world. Accordingly, an influenza vaccine that ensures protection with only a single dose would be a much more cost effective approach to influenza prophylaxis. Generation of Influenza non-replicating virus-like particles (VLP) in baculoviral expression system is an attr...
متن کاملThe active sites of the beta-lactamases of Streptomyces cacaoi and Streptomyces albus G.
The active-site serine of the extracellular beta-lactamases of Streptomyces cacaoi and Streptomyces albus G has been labelled with beta-iodopenicillanate. The determination of the sequence of the labelled peptides obtained after trypsin digestion of the denatured proteins indicate both enzymes to be class A beta-lactamases. Surprisingly the two Streptomyces enzymes do not appear to be especiall...
