SpyTag codon optimized for CHO expression

The SpyTag is a short, unfolded peptide that can be genetically fused to exposed positions in target proteins. It is used in the construct to recognize the corresponding molecule, Catcher, and form a covalent isopeptide bond between the side chains of an reactive aspartate and lysine in SpyCatcher (Hatlem et al. 2019).


Usage and Biology

The SpyTag/SpyCatcher system is based on a modified domain from a streptococcus pyogenes surface protein (SpyCatcher), which recognizes a cognate 13-amino-acid peptide (SpyTag), which can bind spontaneously and form an isopeptide bond (Hatlem et al. 2019).
