strains lacking MalQ and maltose transacetylase are tested for their ability to accumulate maltose. At 1.8 nM external maltose, the ratio of internal to external maltose concentration under equilibrium conditions reaches 10ooooo to 1 but declines at higher external maltose concentrations. The maximal internal level of maltose at increasing external maltose concentrations is around 100 mM
