Summary Introduction

To review:

The reason behind the catalytic activity of ribonucleic acid (RNA) molecules.

Introduction:

Enzymes are protein molecules thatcatalyze the biochemical reactions by lowering down the activation energy. All the enzymes are made up of proteins, except for ribozyme, which is made up of RNA. Ribozymes are found in ribosomes.

Most enzymes are quite specific, catalyzing a particular reaction on a set of substrates that are structurally quite similar to one another. Why are highly specific enzymes advantageous from a biological perspective? They allow catalyzed reactions to produce potentially useful by-products. They allow for the sharing of enzymes by multiple metabolic pathways. They allow an inhibitor to simultaneously inhibit multiple steps in a metabolic pathway. They allow control of which reactions occur at appreciable rates. Why are most enzymes highly specific from a chemical perspective? Enzymes generally requires a tight fit between enzyme and substrate. Interactions between the enzyme and the substrate stabilize the substrate. The active sites of enzymes are always identical in shape to the substrates they bind. The formation of weak interactions between the enzyme and the substrate requires energy.
Streptokinase is an enzyme produced by Streptococci bacteria and is used to digest fibrin clots. It is therefore very effective at eliminating blood clots that cause heart attacks and strokes. Why does a physician not worry that injecting streptokinase will also destroy healthy tissue in their patients? – this answer should discuss the specificity of enzymes for their substrates, defined by the shape of the active site.
Find an enzyme that is used by humans for some industrial or useful process (apart from its original purpose; e.g. food production, textiles, agriculture, clinical diagnosis, medical treatment, biofuel production, material polymerization, etc.).   How do we obtain or harvest the enzyme?   What reaction(s) does it catalyze, and how is this useful for its industrial purpose?   200 words only
