What does gelatinase break down gelatin into?

Gelatinase is an enzyme that specifically breaks down gelatin, a protein derived from collagen. The primary function of gelatinase is to hydrolyze the gelatin molecule, resulting in the release of smaller peptide fragments and ultimately individual amino acids. This process is essential for some bacteria as it allows them to utilize gelatin as a nutrient source for growth and metabolism. Therefore, the breakdown of gelatin by gelatinase leads to the formation of amino acids, which can then be absorbed by the microorganisms for various cellular functions.

Understanding the role of gelatinase is important in bacteriology as it helps identify certain bacterial species based on their ability to liquefy gelatin, further linking enzyme activity to physiological roles of bacteria.
