Site-Directed Mutagenesis: Methods and Applications

Site-directed mutagenesis is a technique conceived in the 70s used to mutate specific DNA sequences in vitro. It relies on synthetic short single-stranded DNA fragments, or oligonucleotides, that contain designated mutations to act as templates in the presence of DNA polymerase enzyme. In the late 80s, Polymerase Chain Reaction (PCR), another laboratory technique, was incorporated into site-directed mutagenesis workflow. The

Factors That Affects Enzyme Activity

Enzymes are a group of proteins that catalyze non-spontaneous chemical reactions in any biological system. In an organism, enzymes function as a group of interconnected chemical reactions in a metabolic pathway, fulfilling a specific cellular task. Metabolic pathways are active under normal circumstances and alter their activities in response to internal and external stimuli. Delayed response or failure to answer

Allosteric Enzymes: Characteristics, Models, and Examples

Introduction: Allosteric enzymes are a group of biocatalysts that possess common characteristics of an enzyme but do not exhibit a typical Michaelis-Menten kinetic behavior. Instead, their kinetics follow a sigmoid curve. The key to allosteric enzyme activity lies in the reversible binding to a specific molecule on a non-catalytic site of the enzyme. The binding initiates the formation of enzyme-substrate

Enzymes as Biocatalysts

Biocatalysts refer to proteins that drive all non-spontaneous chemical reactions in any biological system. Also known as enzymes, they are sensitive to temperature and pH, and act only on their specific reactants, unlike inorganic catalysts. However, their activities can be modulated and controlled. Since enzymes are also active in vitro and are organic in nature, they have been isolated, modified,

Introduction to Enzymology

Enzymology is a field of study that deals with a specific group of proteins called enzymes. These proteins accelerate specific chemical reactions in a biological system, and these reactions are essential to the growth, development, adaptation, and survival of the organism. The absence, accumulation, or dysfunctionality of an enzyme has drastic effects on the living organism, some of which are
