* The differences observed from results published by Vazquez et al. [52] are due to the flexibility impair to the sequence of the CRAC domain. CRAC: cholesterol recognition/interaction amino acid consensus; RTX: Repeat in ToXins; HlyA: alpha-hemolysin; UPEC: uropathogenic Escherichia coli; LtxA: leukotoxin.
