Inhibition by maltotriose and α-methylglucoside of [¹⁴C]maltose transport^a

Inhibition type	Inhibition with strain:
	A15	A24	A64	A60	A179
Avg inhibition by maltotriose (%) ± SD	12 ± 7	16 ± 11	24 ± 4	66 ± 3	59 ± 25
Avg inhibition by α-methyglucoside (%) ± range	23 ± 3	10 ± 10	13	74 ± 3	41

^aTransport of 5 mM [¹⁴C]maltose was measured with the indicated strains (grown on maltose) in the presence or absence of 50 mM maltotriose or 170 mM α-methylglucoside. Where errors are shown, results for maltotriose are averages ± standard deviations (n = 3 to 6) and results for α-methylglucoside are averages of duplicates ± ranges.
