How It Works

Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing attachment of aminoacyl-tRNA to the mRNA-ribosome complex.

Mechanism Steps

1Tetracycline diffuses through the outer membrane of gram-negative bacteria via porin channels.
2Actively transported across the cytoplasmic membrane by a pH-dependent mechanism.
3Binds reversibly to the 30S ribosomal subunit.
