The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity:
  • processing and translocation of ComGC, ComGD, ComGE and ComGG PubMed
  • Typically cleaves a -Gly-|-Phe- bond to release an N-terminal, basic peptide of 5-8 residues from type IV prepilin, and then N-methylates the new N-terminal amino group, the methyl donor being S-adenosyl-L-methionine (according to Swiss-Prot)

• Protein family: peptidase A24 family (according to Swiss-Prot)
