Substances that can improve enzyme activity

This entry is missing Overview , add relevant content to make the entry more complete, and it can also be upgraded quickly. Hurry up edit Come on!

Under certain conditions, substances that can change the enzyme from inactive to active or increase the enzyme activity are called Enzyme activator 。 Anything that can be improved enzymatic activity Substances are called enzyme activators Enzymatic reaction The addition of enzyme activator in the system can lead to reaction rate Increase of.^[1]

Enzyme activator Generally, it can be divided into Required Activator And Non essential activator 。

Chinese name: activator
Foreign name: activator
Alias: Activator

Meaning: A substance that changes an enzyme from inactive to active or increases its activity
component: Ions Or simple Organic compound

Activator（ activator ）Most are Ions Or simple Organic compound 。 Activator press Molecular size It can be divided into three categories: (1) Inorganic ion , such as cation (Most are metal ion ）(K+, Mg2+, Ca2+, etc.) anion (Br -, Cl -, etc.) Hydrogen ion Etc; (2) Organic molecule , such as glutathione ， EDTA ( EDTA ）Etc; (3) protein etc. Biomacromolecule , such as Zymogen activation 。

It can also be divided into essential Activator and Not required activator. Among them, most metal ion activators Enzymatic reaction It is indispensable. If it is not added, the enzyme activity will not be measured, and it is an essential activator. essential The activator itself does not convert into products (before and after reaction Quality and quantity None changed) 。 Not required The activator is activated by combining with the enzyme or substrate or Enzyme substrate complex To improve enzyme activity, while essential Activators act like substrates and participate in the binding reaction between enzyme and substrate or enzyme substrate complex.

Action characteristics

edit

Many enzymes can only show catalytic activity or raise the catalytic activity to the normal and required level when an appropriate activator exists, which is called the Activation
The continuous increase of the amount of necessary activator within a certain range (the value has exceeded 0) may lead to the continuous increase of catalytic activity
Enzyme has certain selectivity to activator. One activator can activate one enzyme and may inhibit another enzyme
Some ions have Antagonism
Some metal ion activators can replace each other
The action of activator is often related to its concentration
The action mechanism of activator is various
