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

A new chromogenic substrate that is blocked at the nonreducing end, 4,6-benzylidene-alpha-D-4-nitrophenylmaltoheptaoside, is used to determine alpha-amylase (EC 3.2.1.1) activity in serum in a coupled assay with alpha-glucosidase (EC 3.2.1.20) and glucoamylase (EC 3.2.1.3) as auxiliary enzymes. The duration of

Isoforms AMY1, AMY2-1 and AMY2-2 of barley alpha-amylase were purified from malt. AMY2-1 and AMY2-2 are both susceptible to barley alpha-amylase/subtilisin inhibitor. The action of these isoforms is compared using substrates ranging from p-nitrophenylmaltoside through p-nitrophenylmaltoheptaoside. The kcat/Km values are
