SPYCatcher -> BaCBM2

Usage and Biology

BaCBM2 is a Carbonhydrate-binding Module family 2(CBM2) derived from Bacillus anthracis[1]. CBMs are protein domains mainly found in carbohydrate-active enzymes.

As our project involves connecting different proteins, we decided to use the SpyTag/SpyCatcher system and have inserted the SpyCatcher at the N-terminal of the BaCBM2.

We insert this part in pET-11a plasmid between BamHI and NdeI restriction sites.

Expression

  • Cells were grown in 200ml LB media (100μg/ml Ampicillin) at 37oC shaking at 140 rpm to an OD600 of 0.5, verifying via a spectrophotometer.
  • Protein was expressed in 0.1mM IPTG for 2hours.
