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

Human salivary alpha-amylase participates in the initial digestion of starch and may be involved in the colonization of viridans streptococci in the mouth. To elucidate the role of histidine residues located near the starch-binding site on the streptococcal-binding activity, the

Human non-salivary, non-pancreatic alpha-amylase (yHXA) is the gene product of a newly found human alpha-amylase gene expressed in yeast. Its mode of action on a fluorogenic derivative of p-nitrophenyl alpha-maltopentaoside, FG5P (FG-G-G-G-G-P), was examined at various pH values to elucidate

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.
