Isomerism, linkage

The first and most extensively examined system was the hydrolytic enzyme papain. A variety of isomeric a-bromoacetylisoalloxazines were used to selectively tether a flavin moiety to the active site cysteine residue. Different isomeric linkages were proposed to allow orientations of the flavin relative to the substrate binding site which would favor reactions with a bound substrate [65]. [Pg.26]

These examples of this methodology show the usefulness of MS/MS, especially in the case of mixtures isomeric linkages can be identified peptide sequences (during either spontaneous or collisional-induced decompositions) can be determined. [Pg.227]

In a second type of structural isomerism, linkage isomerism, the composition of the complex ion is the same, but the point of attachment of at least one of the ligands differs. Two ligands that can attach to metal ions in different... [Pg.951]
