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.
