The E. coli O18ac:K1:H7 NMEC ecpABCDE(matBCDEF) genes are all individually required for E. coli common pilus (ECP) formation in the pathogenic E.coli NMEC strains and ECP production enhances low-temperature biofilm formation in NMEC and and also in K-12 when the silent ecp operon is expressed (Pouttu, 2001; Lehti, 2010; Garnett, 2012). The first 27 aa of EcpE are predicted to be a type I signal peptide. Pfam PF00345 member. ecpB and ecpE are paralogs.
