Our New Basic Parts


We developed 4 new basic parts to contribute to the 2024 iGEM registry this year. Each of them was codon optimized for E. coli.

  • This includes an aprotinin coding sequence, which encodes for a serine protease inhibitor. This was performed because the previous team working on a part that also encoded for aprotinin did not properly list all of their modifications on their part page.
  • We consider our most important basic part to be added is the destructin-1 coding sequence which creates a serine protease, the main enzyme that P. destructans uses to degrade collagen and keratin to infect bat hosts1. The full sequence for this protein includes a leader peptide for extracellular secretion, and putative inhibitory peptide that is cleaved to form the mature protein.
  • In addition coding sequences for destructin-2 & destructin-3 have also been added to the registry. They are very similar to destructin-1 with sharing 90% amino acid identity with destructin-2 and 56% with destructin-3. Although we are not focused on generating these proteases within this cycle of the project we hope to characterize them more the following cycle.
  • The goal of these parts is to encourage other teams to potentially try other approaches in inhibiting destructin-(1-3) to be used to counter white nose syndrome.
