| Glossary: |
tetracenomycin F2 = 4-(3-acetyl-4,5,7,10-tetrahydroxyanthracen-2-yl)-3-oxobutanoic acid |
| Other name(s): |
TCM PKS |
| Systematic name: |
malonyl-CoA:acetate malonyltransferase (tetracenomycin-F2-forming) |
| Comments: |
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. |
