KETOACID LYASES Meaning and
Definition
-
Ketoacid lyases, also known as keto acid decarboxylases, are a group of enzymes that belong to the lyase class of enzymes. These enzymes catalyze the removal of carboxyl groups (decarboxylation) from keto acids, resulting in the formation of specific alkenes or aldehydes. The substrates of ketoacid lyases are typically alpha-keto acids, which are organic compounds containing both a carbonyl group (C=O) and a carboxyl group (COOH) attached to the same carbon atom.
Ketoacid lyases play a crucial role in various metabolic pathways, including amino acid metabolism and the tricarboxylic acid cycle (also known as the Krebs cycle). By catalyzing the decarboxylation of alpha-keto acids, these enzymes contribute to the conversion of organic molecules and the production of energy. Additionally, ketoacid lyases are involved in the biosynthesis of important compounds such as vitamins and cofactors.
The activity of ketoacid lyases requires the presence of cofactors, such as pyridoxal phosphate (PLP) or thiamine pyrophosphate (TPP). These cofactors participate in the catalytic process by stabilizing and activating the substrates, allowing the decarboxylation reaction to occur.
Overall, ketoacid lyases are essential enzymes involved in the metabolism of various substances and are important for the proper functioning of living organisms. Their ability to remove carboxyl groups from keto acids contributes to the generation of important intermediates and energy production pathways.

Etymology of KETOACID LYASES
The word "ketoacid lyases" has its etymology rooted in Greek and Latin.
The term "ketoacid" is a combination of the Greek word "keto-" (meaning "ketone" or "compound with a carbonyl group attached to two carbon atoms") and the Latin word "acidus" (meaning "sour" or "acid"). The word "ketone" refers to a functional group in organic chemistry that contains a carbonyl group bonded to two carbon atoms.
The word "lyases" comes from the Greek word "lysis" (meaning "loosening" or "splitting"). In biochemistry, the term "lyase" refers to an enzyme that catalyzes the breaking of chemical bonds, causing a molecule to split into two or more smaller molecules.
