3.A.1.1.52
Sugar (sucrose, maltose, glucose, fructose, esculin (coumarin β-glucoside)) uptake system possibly consisting of 5 or 6 proteins (see below) (Nieves-Morión and Flores 2017). These proteins are all implicated in sugar uptake, but they may include components of multiple transporters. The system may also regulate formation of septal nanopores (Flores et al. 2018).
