antibiotic catabolic process

Definition

Target type: biologicalprocess

The chemical reactions and pathways resulting in the breakdown of antibiotic, a substance produced by or derived from certain fungi, bacteria, and other organisms, that can destroy or inhibit the growth of other microorganisms. [GOC:go_curators]

Antibiotic catabolism is a complex biological process involving the breakdown of antibiotic molecules by microorganisms. It is a vital mechanism for bacterial survival, as antibiotics are designed to inhibit bacterial growth. The process typically involves multiple steps, including:

1. **Antibiotic Uptake:** The first step is the entry of the antibiotic into the bacterial cell. This can occur through passive diffusion, active transport, or facilitated diffusion. The efficiency of antibiotic uptake can vary depending on the type of antibiotic and the bacterial species.

2. **Antibiotic Modification:** Once inside the bacterial cell, antibiotics can be modified by enzymatic reactions. These modifications often involve enzymatic inactivation of the antibiotic, rendering it ineffective. For example, some bacteria produce enzymes that acetylate, phosphorylate, or glycosylate antibiotic molecules, thereby reducing their affinity for their bacterial targets.

3. **Antibiotic Degradation:** In some cases, the modified antibiotic molecules can be further degraded into smaller, non-toxic products by enzymatic reactions. This degradation process can involve hydrolytic cleavage, oxidation, or reduction reactions. The breakdown products are then either excreted from the cell or used as carbon sources for bacterial growth.

4. **Efflux Pumps:** Many bacteria possess efflux pumps, membrane proteins that actively pump out antibiotics from the cell. These pumps can recognize and remove a wide range of antibiotics, effectively preventing them from reaching their targets within the cell.

5. **Target Modification:** Some bacteria can alter the structure of their cellular targets that antibiotics interact with, rendering the antibiotic ineffective. For example, mutations in the bacterial ribosome can lead to resistance to certain antibiotics.

Antibiotic catabolism can be highly specific, with different bacteria employing different mechanisms to inactivate specific antibiotic classes. The evolution of antibiotic resistance mechanisms, including catabolic pathways, is a significant challenge in medicine, as it can render antibiotics ineffective and lead to the emergence of antibiotic-resistant infections.'
