Tolq - The tolQ allele in P90C is tolQ13, an amber mutation in codon 36 of tolQ that has been shown to reduce transcription of tolA by ≈ 50% (Vianney et al., 1996). Thus, the phenotype of the tolQ mutation regarding O7 LPS surface expression can be explained by a polar effect on tolA gene expression.
