The determination of the lysozyme activity using the bacterial electrode (see p. 139) can also be used for immuno-analysis of biotine and avidine. The determination is based on the inhibition reaction of avidine with the biotine-lysozyme conjugate. After the reaction, the conjugate is no longer capable of dissolving the cell wall of the bacteria. The determination of biotine is similar [15]. 

Terminal L-arabinosidic linkages in L-arabinose conjugates are also hydrolyzed by the enzyme. The enzyme of R. fiava releases L-arabinose from the polysaccharide of the water shield (Brasenia schreberi J. F. Gmel)38 and from the cotyledon of Tora bean (Phaseolus vulgaris).39 Some 70 to 80% of the side chains of the arabinoxylan in rice cell-wall are composed of L-arabinose. When the a-L-arabinofuranosidase from R. 

Bacterial lipoproteins (LP) are structural components of bacterial cell walls consisting of an S-glycerylcysteine moiety, where the glyceryl moiety is di-O-acylated and the cysteine residue is conjugated to the amino-terminus of various polypeptides. In addition, the cysteine a-amine may be acylated with an... 

Antibodies are bound to a solid-phase matrix. Protein A or G beads are commonly used. Proteins A and G are polypeptides located on the cell wall of some bacteria. These proteins bind the Fc (constant) region of antibodies without affecting the ability of the antibodies to bind antigen. Proteins A and G are commercially available conjugated to sepharose, agarose, or acrylic beads. A chromatographic column is prepared with the tertiary complex (antibody-Protein A/G-solid matrix). 

More detailed discussion of food polymers and their functionality in food is now difficult because of the lack of the information available on thermodynamic properties of biopolymer mixtures. So far, the phase behaviour of many important model systems remains unstudied. This particularly relates to systems containing (i) more than two biopolymers, (ii) mixtures containing denatured proteins, (iii) partially hydrolyzed proteins, (iv) soluble electrostatic protein-polysaccharide complexes and conjugates, (v) enzymes (proteolytic and amylolytic) and their partition coefficient between the phases of protein-polysaccharide mixtures, (vi) phase behaviour of hydrolytic enzyme-exopolysaccharide mixtures, exopolysaccharide-cell wall polysaccharide mixtures and exopolysaccharide-exudative polysaccharide mixtures, (vii) biopolymer solutes in the gel networks of one or several of them, (viii) enzymes in the gel of their substrates, (ix) virus-exopolysaccharide, virus-mucopolysaccharides and virus-exudative gum mixtures, and so on.
