title: Introduction of gamma-glutamyl residue into chymotrypsin and agarose gel: application to cross-linking and immobilization of protein.
abstract: In our previous work a new method for the cross-linking of protein was proposed. The method is based on the spontaneous chelate formation process between salicylaldehyde and alpha-amino acid residues. Thus, the facile procedure for the introduction of these residues into protein is required. In this paper, a modification reagent which affords gamma-glutamylation products, i.e., introducing an alpha-amino acid functional group to the protein was proposed. Versatility of the reagent for the preparation of a cross-linked enzyme was examined.
