1. Target Selection: Blocking the Copy Machine
To multiply and spread, bacteria must constantly unzip and replicate their DNA strands. Ciprofloxacin targets and binds to two vital bacterial enzymes responsible for this process:
- DNA Gyrase: The enzyme that unwinds and untangles DNA loops so they can be read.
- Topoisomerase IV: The enzyme that separates the newly copied bacterial DNA into two fresh cells.
