Enzyme Catalysis,Regulation of Enzymatic Activity

Enzyme Catalysis
Regulation of Enzymatic Activity

There are two general ways to control enzymatic activity.

  1.  Control the amount or availability of the enzyme.

  2.  Control or regulate the enzymes catalytic activity.

Each topic can be subdivided into many different categories.

Enzyme amounts in a cell depend upon the rate in which it is 

synthesized and the rate it is degraded.  Synthesis rates can be 

transcriptionally or translationally controlled.  Degradation rates of 

proteins are also controlled.

However, We will be focusing on the regulation of enzymatic

 activity.

Enzymatic catalysis and 

mechanisms

•A. Acid - Base catalysis

•B.  Covalent catalysis

•C.  Metal ion aided catalysis

•D. Electrostatic interactions

•E.  Orientation and Proximity effects

•F.  Transition state binding

General Acid Base

Rate increase by partial proton abstraction by a Bronsted base 

  or

Rate increase by partial proton donation by a Bronsted Acid
