The minimized SpyCatcher

Minimization

The SpyCatcher is a highly functional Tag intended for translational fusion to a target protein. Unfortunately its size (116 amino acid) is quite large and can therefor hinder the native folding and successfull secretion of the protein of interest. The 2017 team of [https://2017.igem.org/Team:TU_Dresden TU_Dresden] submitted a minimized version of the SpyCatcher to the registry to ensure the effective [https://2017.igem.org/Team:TU_Dresden/Project/Secretion secretion] necessary for their project. The mini. SpyCatcher is 32 amino acids shorter but still fully functional, which was proven by TU_Dresden team (see Application) as well as by the [https://www.ncbi.nlm.nih.gov/pubmed/24161952 researchers]that proposed the minimization.

Codon adaption

The original part was used in E. coli but the mini. SpyCatcher was implemented in B. subtilis so the code was adapted to its codon usage. The sequence was proposed by [https://www.ncbi.nlm.nih.gov/pubmed/28230977 researchers]that investigated the secretion of SpyCatcher fusion proteins with B. subtilis.

His-Tag:

The mini. SpyCatcher was also submitted to the [http://parts.igem.org/Part:BBa_K2273171 registry] with an added C-terminal His-Tag to purify the protein constructs.
