    摘要: Biotin-binding modified avidin-type molecules are provided in which the essential tyrosine residue in the biotin-binding site is modified in such a way that its pKa is decreased in comparison to the pKa of the unmodified tyrosine residue in the corresponding unmodified avidin-type molecule. The avidin-type molecules include: (i) native egg-white avidin; (ii) recombinant avidin; (iii) deglycosylated forms of avidin; (iv) bacterial streptavidin; (v) recombinant streptavidin; (vi) truncated streptavidin; and (vii) derivatives of (i)-(vi) which are modified at sites other than the essential tyrosine residue. The modification is achieved by substitution at one or both ortho positions to the hydroxy radical of the tyrosine residue by radicals such as nitro, halogen, azo and amino. The modified avidin-type molecules can be used in all applications of the avidin-biotin technology.

    摘要: Immobilized garlic alliinase wherein the alliinase is chemically, physically or biologically immobilized, is useful in a method for continuous production of allicin. The method comprises adding a solution of alliin as substrate to a column containing the immobilized garlic alliinase and collecting pure allicin in the effluent. The pure allicin is intended for use as food additive or for the preparation of pharmaceutical compositions for the treatment of viral, bacterial, fungal and parasitic infections, high levels of cholesterol and blood lipids, high blood pressure and thrombosis.
