Oligopeptide mapping of NP proteins of influenza A viruses. 1982

B P Sokolov, and V M Zhdanov

Oligopeptide mapping of nucleoproteins (NP proteins) of 54 strains of influenza A virus showed the presence of both common and individual oligopeptides. Using the distribution of variable oligopeptides as the criterion, NP proteins were subdivided into four groups (NP0, NP1, NP2 and NP3). The NP0 group is composed of H0N1 influenza viruses and the majority of animal influenza viruses. The NP1 group contains H1N1 (except A/California/78) and H2N2 influenza viruses isolated from man as well as H1N1 influenza viruses recently isolated from animals. A/New Jersey/76 (Hsw 1N1) influenza virus also belongs to the NP1 group. The NP2 group consists of H3N2 influenza viruses isolated from man and animals. A/California/78 (H1N1) influenza virus also falls into the NP2 group. The NP3 group contains NP proteins of four animal influenza viruses with antigenic formulas Hsw1N2, Hsw1Nav2, Hav6Nav5 and Heq2Neq2.

UI	MeSH Term	Description	Entries
D009698	Nucleoproteins	Proteins conjugated with nucleic acids.	Nucleoprotein
D009980	Influenza A virus	The type species of the genus ALPHAINFLUENZAVIRUS that causes influenza and other diseases in humans and animals. Antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. Transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). Infected birds shed the virus in their saliva, nasal secretions, and feces.

D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
