Proteoglycan: Proteoglycans are proteins that are heavily glycosylated. The basic proteoglycan unit consists of a "core protein" with one or more covalently attached glycosaminoglycan (GAG) chain(s).Chondroitin sulfate proteoglycan: Chondroitin sulfate proteoglycans (CSPGs) are proteoglycans consisting of a protein core and a chondroitin sulfate side chain. They are known to be structural components of a variety of human tissues, including cartilage, and also play key roles in neural development and glial scar formation.Canine hepacivirus: Canine hepacivirus is a single strand RNA virus of the genus Hepacivirus.Kapoor A, Simmonds P, Gerold G, Qaisar N, Jain K, Henriquez JA, Firth C, Hirschberg DL, Rice CM, Shields S, Lipkin WI (2011) Characterization of a canine homolog of hepatitis C virus.HHV capsid portal protein: HHV Capsid Portal Protein, or HSV-1 UL-6 protein, is the protein which forms a cylindrical portal in the capsid of Herpes simplex virus (HSV-1). The protein is commonly referred to as the HSV-1 UL-6 protein because it is the transcription product of Herpes gene UL-6.Coles PhillipsHepatitis B virus precore mutant: A precore mutant is a variety of hepatitis B virus that does not produce hepatitis B virus e antigen (HBeAg). These mutants are important because infections caused by these viruses are difficult to treat, and can cause infections of prolonged duration and with a higher risk of liver cirrhosis.Thomas Abney (judge): Sir Thomas Abney (1690 or 1691 – 1750) was an English barrister and later judge. He was the younger son of Sir Edward Abney (who in turn was the elder brother of Sir Thomas Abney, Lord Mayor of London), by his second wife, Judith, daughter and co-heir of Peter Barr, of London.Generalized vaccinia: Generalized vaccinia is a cutaneous condition that occurs 6-9 days after vaccination, characterized by a generalized eruption of skin lesions, and caused by the vaccinia virus.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.Hexon protein: In molecular biology, the hexon protein is a major coat protein found in Adenoviruses. Hexon coat proteins are synthesised during late infection and form homo-trimers.Symmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Vpx: Vpx is a virion-associated protein encoded by human immunodeficiency virus type 2 HIV-2 and most simian immunodeficiency virus (SIV) strains, but that is absent from HIV-1. It is similar in structure to the protein Vpr that is carried by SIV and HIV-2 as well as HIV-1.
