This page contains a list of the contents for an antibiotic-resistance "catalog" page. The actual layout will be developed on New Catalog Page for Antibiotic Resistance Parts.

Introduction to Antibiotic Resistance

The established mechanisms of antibiotic resistance include the following:

1. Enzymes that inactivate the antibiotic [famously (a). beta-lactamases that destroy penicillins and related compounds and (b) enzymes that acetylate chloramphenicol].
2. Proteins that keep antibiotics out of the cell (by blocking the outer-membrane pores).
3. Membrane-embedded channel proteins that actively pump antibiotics out of the cell.
4. Proteins (and RNAs) with altered drug binding sites. (Vancomycin resistance comes from a switch in the chemistry of the cell-wall cross-linking peptide). This category also includes mutations in ribosomal RNA -- ribosomes are one of the main targets of both prokaryote- and eukaryote-directed antibiotics.
5. Proteins that enable substitution of an alternative metabolic pathway (as in the case of sulfonamide resistance).
