The method of assay of neutral alpha-glucosidase from human kidney and urine using beta-maltosides (p-nitrophenyl-beta-D-maltoside [NP-beta-D-maltoside], 2-chloro-4-nitrophenyl-beta-D-maltoside]) [CNP-beta-D-maltoside] and 4-methylumbelliferyl-beta-D-maltosides ([MU-beta-D-maltoside]) as substrates and beta-glucosidase as an auxiliary enzyme is proposed. All three beta-maltosides are suitable substrates for the determination

In wild-type Escherichia coli the activity of the maltose transport system is dependent on a periplasmic maltose-binding protein. It has been possible, however, to isolate mutants in which transport activity is mediated by the membrane components of the system and
