A multi-domain polyketide synthase involved in the synthesis of tetracenomycin in the bacterium Streptomyces glaucescens. It involves a ketosynthase complex (TcmKL), an acyl carrier protein (TcmM), a malonyl CoA:ACP acyltransferase (MAT), and a cyclase (TcmN). A malonyl-CoA molecule is initially bound to the acyl carrier protein and decarboxylated to form an acetyl starter unit. Additional two-carbon units are added from nine more malonyl-CoA molecules.

Substrates: TcmN is a bifunctional protein that catalyzes the regiospecific cyclization of the linear decaketide (bound to the multi-domain polyketide synthase) to tetracenomycin F2 and the O-methylation of tetracenomycin D3 to tetracenomycin B3 Products: -
