DEFINITION

Classification: 530/367

Ovalbumin, e.g., avidin, conalbumins, etc.:

(under subclass 362) Proteins having the structure of ovalbumin and compounds derived from these by addition to or deletion of parts of the polypeptiede structure.

(1) Note. Physical Properties. Numbers of residue: 400. Molecular Weight: 45,000. Structure is a complex protein consisting of a single polypeptide chain of about 400 residues, a minimum of two phosphate residues per mole, and an oligo-saccharide side chain composed of only mannose and glucosamine residues.

(2) Note. Source. Ovalbumin, comprises 75 percent of the protein of egg white from hen's eggs where it occurs with avidin, lysozyme, conalbumin and ovomacoid.

(3) Note. Synonyms: egg albumin, ovalbumin

(4) Note. CA Registry Number of unmodifed form: [figure]

(5) Note. Physical Properties. Chicken Avidin. Number of Residues: 128. Molecular Weght: 14,332 structure is a glycoprotein containing four essentially identical subunits: With a combined molecular weight of about 66,000. Each

subunit is a single polypeptide chain containing 128 amino acid residues with alanine at the N-terminal, glutamic acid at the C-terminal, and a carbohydrate moieity attached at the asparaginly residue position 17.

(6) Note. Avidin. Source. Isolated from raw egg white protein of eggs of birds and amphibia. (7) Note. Avidin CA Registry Number of form: [figure]
