Q11. Nucleotide sequence similarity searches confirm that the yellow genes in the pathogenicity island encode factors that are not normally found in E. coli . Experimental deletion of the yellow genes results in a diminished immune response in a mouse model of GPEC infection. The yellow genes most likely encode:
