SUBTILISIN A Meaning and
Definition
-
Subtilisin A is a peptidase, which is an enzyme that catalyzes the hydrolysis of peptide bonds in proteins. It is derived from Bacillus subtilis, a bacterium commonly found in soil and in the intestinal tracts of animals. Subtilisin A is a well-known and widely used enzyme in various industrial applications, including the production of detergents, food processing, and the pharmaceutical industry.
This enzyme belongs to the serine protease family, characterized by the presence of a catalytic triad composed of three amino acids: serine, histidine, and aspartate. The serine residue acts as a nucleophile, initiating the process of protein degradation by attacking and breaking the peptide bond. Subtilisin A specifically cleaves peptide bonds adjacent to large, hydrophobic amino acid residues, such as alanine, valine, and leucine.
Due to its robust activity, stability, and broad substrate specificity, subtilisin A is widely used as a biocatalyst in numerous industrial processes. For example, in laundry detergents, this enzyme efficiently degrades protein-based stains, such as blood, grass, and food residues. In the food industry, subtilisin A is employed in processes such as cheese production and meat tenderization. Additionally, it is utilized in the pharmaceutical industry for the synthesis of peptide-based drugs.
In summary, subtilisin A is a serine protease derived from Bacillus subtilis that plays a key role in various industrial applications by catalyzing the hydrolysis of peptide bonds in proteins.
Common Misspellings for SUBTILISIN A
Etymology of SUBTILISIN A
The word "subtilisin" comes from the Latin word "subtilis", meaning "fine" or "delicate". "Subtilisin" is a term used for a class of enzymes that are proteases, meaning they break down proteins by cleaving peptide bonds. The "A" in "Subtilisin A" refers to a specific subclass of subtilisin enzymes.
