Teicoplanin complex is a mixture of closely related metabolites produced by A. teichomyceticus that are effective against Gram-positive bacteria. Teicoplanin A2, the major component of this complex, is a glycopeptide antibiotic structurally similar to vancomycin that prevents bacterial cell-wall synthesis by binding and sequestering a cell-wall precursor with a D-alanine-containing peptide.
