| + | [https://www.uniprot.org/uniprot/TCMN_STRGA TCMN_STRGA] The N-terminal domain enhances the formation of an early, partially cyclized intermediate, while the C-terminal domain catalyzes the 3-O-methylation of one or more later intermediates in the biosynthetic pathway. Catalyzes the methylation of tetracenomycin D3 (Tcm D3) to yield Tcm B3. Catalyzes as well the following side reactions: methylation of 8-O-methyl-Tcm D3 to yield Tcm E; and of 9-carboxymethyl-Tcm B3 to yield Tcm A2. | ||
