Rapid Paper Identification of the Soybean Allergenic Protein, Gly m Bd 30K, with the Soybean Seed 34-kDa Oil-body-associated Protein
Biosei. Biosech. Biochem., 57 (6), 1030-1033, 1993,-0001,():
The soybean allergenic protein, Glym Bd 30K[Ogawa et al., J. Nutr. Sci. Vitaminol., 37, 555-565 (1991)]which is most strongly and frequently recognized by the IgE antibodies in sera of soybean-sensitive patients with atopic dermatitis, has been characterized, The allergen was isolated from the crude 7S-globulin fraction as an oligomerie form with a molecular weight of more than 3000,000 by gel-filtration chromatography. On two-dimensional gel electrophoresis, the native oligomeric allergen had an isoelectricpoint of about pH 4.5 and was dissociated into a monomeric form with a molecular weight of about 32,000 by the treatment with sodium dodeeyl sulfate and 2-mercaptoethanol. The monomeric allergen had an N-terminal amino acid sequence and amino acid composition identical with those of the soyhean seed 34-kDa oil-body-associated protein or the soybean vacuolar protein P34 with close homology to papain-like thiol proteinases[Kalinski et al., J. Biol. Chem., 267, 12068 (1992)]. The identity was further confirmed by the 34-kDa oil-body-associated protein. By this observation, Gly m Bd 30K was shown to have about 30% sequence homology with Der pI, a house dust mite allergen that is a thiol proteinase from Dermatophagoides pteronyssius.
