A role for tRNA modifications in genome structure and codon usage.

abstract：:Most bacteria that colonize eukaryotes must bind directly to host cells to establish a replicative niche. In enteric bacteria, adhesion to host cells is often promoted by a lectin found on surface-localized pili. Some pili promote efficient adhesion only when they are subjected to shear stress, as found during the flo...
