Streptolydigin (Stl) is an antibiotic that works by inhibiting nucleic acid chain elongation by binding to RNA polymerase, thus inhibiting RNA synthesis inside a cell. [1] [2] [3] Streptolydigin inhibits bacterial RNA polymerase, but not eukaryotic RNA polymerase. [4] It has antibacterial activity against a number of Gram positive bacteria.[ citation needed ]
