Type 1A pilins, also known as fimA proteins, promote bacterial colonization by forming pili, or fimbriae (polar filaments extending from the surface of bacteria, reaching 0.5-1.5 microns in length and 100-300 per cell) . These pili play a crucial role in promoting bacterial adhesion to the epithelium of specific host organs. Type-1A pilin/fimA Protein, E.coli (His-SUMO) is the recombinant E. coli-derived Type-1A pilin/fimA protein, expressed by E. coli , with N-His, N-SUMO labeled tag.
