1. Soluble proteins showing binding activity to 2-isobutyl-3-methoxypyrazine have been purified to homogeneity from rabbit and pig nasal tissue; their characteristics are similar to the bovine odorant-binding protein and are to be considered members of the same family. 2. The rabbit protein is a homodimer with subunits of M(r) 19k and an isoelectric point of 4.7, whereas the pig protein appears to consist of a single polypeptide chain of M(r) 22k and an isoelectric point of 4.2. 3. Both proteins bind 2-isobutyl-3-methoxypyrazine with dissociation constants in the micromolar range. 4. Antibodies against the bovine OBP react well with the rabbit protein, and slightly with the porcine one.

Abstract
1. Soluble proteins showing binding activity to 2-isobutyl-3-methoxypyrazine have been purified to homogeneity from rabbit and pig nasal tissue; their characteristics are similar to the bovine odorant-binding protein and are to be considered members of the same family. 2. The rabbit protein is a homodimer with subunits of M(r) 19k and an isoelectric point of 4.7, whereas the pig protein appears to consist of a single polypeptide chain of M(r) 22k and an isoelectric point of 4.2. 3. Both proteins bind 2-isobutyl-3-methoxypyrazine with dissociation constants in the micromolar range. 4. Antibodies against the bovine OBP react well with the rabbit protein, and slightly with the porcine one.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
