RESUMO

Staphylococcus lugdunensis and Corynebacterium amycolatum each have a Na+/glutamine cotransporter that displays an ordered reaction sequence at the extracellular surface, with sodium binding (Km of 6.5 mM) before glutamine (Km of 50 μM). Asparagine is low-affinity substrate (Km ≈ 1 mM) for each system.
