Amino acid sequences of glycopeptides obtained from basic proline-rich glycoprotein of human parotid saliva. 1983

H Shimomura, and Y Kanai, and K Sanada

A proline-rich glycoprotein, in which proline, glutamic acid, and glycine represent about 80 per cent of the total residues, was obtained from human parotid saliva. The amino acid sequences of glycopeptides obtained from digests of the glycoprotein with clostripain were determined to be Pro-Gly-Lys-Pro-Glu-Gly-Pro-Pro-Pro-Gln-Gly-Gly-Asn(CHO)-Gln-Ser-Gln-Gly-Pro- Pro-Pro-Arg and Pro-Pro-Gln-Gly-Gly-Asn(CHO)-Gln-Ser-Gln-Gly-Pro-Pro-Pro-His-Pro-Gly-Lys-Pro -Glu-Arg. The structural relationship between the glycopeptides and the known salivary peptide is discussed.

UI	MeSH Term	Description	Entries
D010306	Parotid Gland	The largest of the three pairs of SALIVARY GLANDS. They lie on the sides of the FACE immediately below and in front of the EAR.	Gland, Parotid,Glands, Parotid,Parotid Glands
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
D002621	Chemistry	A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D006020	Glycopeptides	Proteins which contain carbohydrate groups attached covalently to the polypeptide chain. The protein moiety is the predominant group with the carbohydrate making up only a small percentage of the total weight.	Glycopeptide

D055232	Proline-Rich Protein Domains	Protein domains that are enriched in PROLINE. The cyclical nature of proline causes the peptide bonds it forms to have a limited degree of conformational mobility. Therefore the presence of multiple prolines in close proximity to each other can convey a distinct conformational arrangement to a peptide chain.
