Bacterial GAG genetic clusters. (A) Genetic cluster of Streptococcus agalactiae/Streptococcus pneumoniae. (B) Genetic cluster of Streptobacillus moniliformis. Genes for GAG depolymerization, degradation, and metabolism, except for import, are well conserved between the two bacterial clusters. Genetic clusters of Streptococcus and Streptobacillus encode PTS and the solute-binding protein-dependent ABC transporter, respectively, as an importer.
