Trim21-(GGGGS)3-Coh2

This parts code for the trim21 E3 ligase having his PRYSPRY domain truncated (BBa_K3396007), fused to type 1 Cohesin module derived from Clostridium thermocellum cellulosome scaffoldin using Glycine serine flexible linker repeated three times to maintain part flexibility needed during target ubiquitination
