Implication

In vitro study reveals that primary amines require unbranched chains exceeding four carbons for transglutaminase coupling, indicating potential for site-specific protein functionalization.

Key Points

To determine the substrate specificity of transglutaminase for primary amines in order to facilitate the targeted incorporation of functional groups into proteins and peptides.
Evaluated catalytic activity using microbial transglutaminase and guinea pig liver transglutaminase.
Tested the incorporation efficiency of diverse primary amine structures into the model peptide benzyloxycarbonyl-L-Gln-Gly (Z-Gln-Gly).
Primary amines required an unbranched chain of more than four carbons between functional groups to be successfully coupled to Z-Gln-Gly.
Primary amines containing appropriate aliphatic spacers successfully introduced carboxyl groups, phosphate groups, and saccharides into protein substrates.
