E faecalis OG1RF_11616 encodes PTS-glucosamine. (A–F) Growth curves of E faecalis OG1RF or OG1RFΔ11616 in minimal media containing the indicated carbohydrate as the primary carbon source. (n = 3 cultures per strain, data are presented as means ± SD although error bars are not visible because of their small height, ∗P < .05). (G) OG1RF_11616 mRNA abundance in E faecalis growing in minimal media containing the indicated carbohydrate as the primary carbon source (n = 3 cultures per group per time point, data presented as means ± SD, ∗P < .05 glucosamine vs others, Student t test).
