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

The X-ray structure analysis of a crystal of pig pancreatic alpha-amylase soaked with a rho-nitrophenyl-alpha-D-maltoside (pNPG2) substrate showed a pattern of electron density corresponding to the binding of a rho-nitrophenol unit at subsite -2 of the active site. Binding 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

The effect of chemical modification of lysine residues on the activity of porcine pancreatic alpha-amylase (PPA) was examined, using p-nitrophenyl-alpha-D-maltoside, p-nitrophenyl-alpha-D-maltotrioside, phenyl-alpha-D-maltoside and phenyl-alpha-D-maltotrioside as substrates. Chemical modification of PPA with trinitrobenzenesulfonic acid enhanced the kcat/Km values for p-nitrophenyl substrates
