Maltose phosphorylase

Maltose phosphorylase cannot carry out a similar reaction. The P exchange reaction of sucrose phosphorylase is accounted for by a double-displacement mechanism where E = E-glucose ... [Pg.454]

Maltose phosphorylase proceeds via a single-displacement reaction that necessarily requires the formation of a ternary maltose E Pi (or glucose E glucose-l-phosphate) complex for any reaction to occur. Exchange reactions are a characteristic of enzymes that obey double-displacement mechanisms at some point in their catalysis. [Pg.454]

CL emission. The system allows a simple determination of phosphate in 3 min with a linear range of 4.8-160 pM. Owing to its sensitivity, this method could be satisfactorily applied to the analysis of maximum permissible phosphate concentrations in natural waters [42-44], Also, the maltose-phosphorylase, mutar-ose, and glucose oxidase (MP-MUT-GOD) reaction system combined with an ARP-luminol reaction system has been used in a highly sensitive CL-FIA sensor [45], In this system, MP-MUT-GOD is immobilized on A-hydroxysuccinimide beads and packed in a column. A linear range of 10 nM-30 pM and a measuring time of 3 min were provided, yielding a limit of detection of 1.0 pM as well as a satisfactory application in the analysis of river water. [Pg.578]

The detection scheme based on maltose phosphorylase, mutarotase and glucose oxidase with chemiluminescence detection and implemented into an FIA system has been thoroughly investigated on freshwater samples [264]. Interferences were eliminated with a cation-exchange resin as the only sample pretreatment and the results of 31 river and pond waters correlate fairly well with the molybdenum assay (r = 0.96) [264]. A laboratory based multichannel FIA equipment has the enz5mies immobihzed in a packed bed... [Pg.110]

Maltose generation is detected by the maltose phosphorylase (EC 2.4.1.8) reaction, which avoids interference by the endogenous glucose of the sample. [Pg.618]
