Functional Family Carminomycin 4-O-methyltransferase DnrK

Enzyme Information

2.1.1.292
Carminomycin 4-O-methyltransferase.
based on mapping to UniProt Q06528
S-adenosyl-L-methionine + carminomycin = S-adenosyl-L-homocysteine + daunorubicin.
-!- The enzymes from the Gram-positive bacteria Streptomyces sp. C5 and Streptomyces peucetius are involved in the biosynthesis of the anthracycline daunorubicin. -!- In vitro the enzyme from Streptomyces sp. C5 also catalyzes the 4-O- methylation of 13-dihydrocarminomycin, rhodomycin D and 10-carboxy- 13-deoxycarminomycin.
