Supplementary Figure S2 from Hemolytic <i>E. coli</i> Promotes Colonic Tumorigenesis in Females

Verification of computational E. coli typing based on fimH mutation patterns. (A) Estimation of the factorization rank r in nonnegative matrix factorization (NMF). NMF analysis using 4 as the factorization rank r revealed that fimH could be classified into four types. (B) Consensus sequence of each type of fimH. Consensus sequences were illustrated by WebLogo using stacks of symbols. The size of symbols indicates the relative frequency of each base at that position.
