EC 2.1.1.335     
Accepted name: 4-amino-anhydrotetracycline N4-methyltransferase
Reaction: (1) S-adenosyl-L-methionine + 4-amino-4-de(dimethylamino)anhydrotetracycline = S-adenosyl-L-homocysteine + 4-methylamino-4-de(dimethylamino)anhydrotetracycline
(2) S-adenosyl-L-methionine + 4-methylamino-4-de(dimethylamino)anhydrotetracycline = S-adenosyl-L-homocysteine + anhydrotetracycline
Glossary: 4-amino-4-de(dimethylamino)anhydrotetracycline = (4S,4aS,12aS)-4-amino-3,10,11,12a-tetrahydroxy-6-methyl-1,12-dioxo-4a,5-dihydro-4H-tetracene-2-carboxamide
4-methylamino-4-de(dimethylamino)anhydrotetracycline = (4S,4aS,12aS)-3,10,11,12a-tetrahydroxy-6-methyl-4-(methylamino)-1,12-dioxo-4a,5-dihydro-4H-tetracene-2-carboxamide
anhydrotetracycline = (4S,4aS,12aS)-4-(dimethylamino)-3,10,11,12a-tetrahydroxy-6-methyl-1,12-dioxo-1,4,4a,5,12,12a-hexahydrotetracene-2-carboxamide
Other name(s): oxyT (gene name); ctcO (gene name)
Systematic name: S-adenosyl-L-methionine:(4S,4aS,12aS)-4-amino-3,10,11,12a-tetrahydroxy-6-methyl-1,12-dioxo-4a,5-dihydro-4H-tetracene-2-carboxamide Nα-methyltransferase
Comments: The enzyme, characterized from the bacterium Streptomyces rimosus, participates in the biosynthesis of tetracycline antibiotics.
