Enzyme Activity

Mind Maps in Clinical Chemistry (Part II), 2021
On the surface of the enzyme is an active site that temporarily binds the reactants or substrates forming an enzyme-substrate complex. The catalytic action of the enzyme then converts the substrate to a product or products.

Enzyme activation for activator and enzyme activity measurement

Biosensors and Bioelectronics, 1993
A new sensing principle of enzyme activation is demonstrated for the determination of glycogen phosphorylase b and its allosteric effector AMP. As the indicator of the phosphorylase catalysed glycogen phosphorolysis, glucose-1-phosphate formation has been detected with an enzyme sequence comprising coentrapped alkaline phosphatase, mutarotase and ...

Effect of arbuscular mycorrhizal fungi on soil enzyme activity is coupled with increased plant biomass

European Journal of Soil Science, 2019
Arbuscular mycorrhizal fungi (AMF) form a mutualistic association with plant roots by improving phosphorus (P) uptake of the host plant. Previous studies demonstrated that AMF exert various influences on soil enzyme activity; however, quantification of ...

Sulfate-activating enzymes

1987
Publisher Summary This chapter discusses the sulfate-activating enzymes. The two sulfate-activating enzymes, ATP-sulfurylase (ATP:sulfate adenylyltransferase; sulfate adenylyltransferase), and APS kinase (ATP: adenylylsuifate 3'-phosphotransferase; adenylylsulfate kinase), catalyze the activation of inorganic sulfate first to APS (adenosine- 5 ...

Analysis of Enzyme Activities

2013
The evaluation of enzyme activities, especially their capacities, represents an important step towards the modelling of biochemical pathways in living organisms. The implementation of microplate technology enables the determination of up to >50 enzymes in relatively large numbers of samples and in various biological materials. Most of these enzymes are

Enzyme activity during germination of different cereals: A review

Food reviews international (Print), 2018
The germination process increases enzymatic activity. However, this does not occur in the same way in all cereals. It depends on the type of enzyme, the cereal, and the conditions of germination.

Photon enzyme activation

Bulletin of Mathematical Biology, 1976
The electromagnetic molecular electronic resonance (EMER) frequencies of the molecular chains of α-chymotrypsin are calculated. The chain length relations and coupling positions suggest a possible energy transfer, at the EMER frequencies, from one chain to the other.
