Accepted name: demethylluteothin O-methyltransferase
Reaction: S-adenosyl-L-methionine + demethylluteothin = S-adenosyl-L-homocysteine + luteothin
Glossary: luteothin = 2-[(3E,5E)-3,5-dimethyl-6-(4-nitrophenyl)hexa-3,5-dien-1-yl]-6-methoxy-3,5-dimethyl-4H-pyran-4-one
aureothin = 2-methoxy-3,5-dimethyl-6-[(2R,4Z)-4-[(2E)-2-methyl-3-(4-nitrophenyl)prop-2-en-1-ylidene]oxolan-2-yl]-4H-pyran-4-one
spectinabilin = neoaureothin = 2-methoxy-3,5-dimethyl-6-[(2R,4Z)-4-[(2E,4E,6E)-2,4,6-trimethyl-7-(4-nitrophenyl)hepta-2,4,6-trien-1-ylidene]oxolan-2-yl]-4H-pyran-4-one
Other name(s): aurI (gene name)
Systematic name: S-adenosyl-L-methionine:demethylluteothin O-methyltransferase
Comments: The enzyme, characterized from the bacterium Streptomyces thioluteus, participates in the biosynthesis of the antibiotic aureothin. An orthologous enzyme in the bacteria Streptomyces orinoci and Streptomyces spectabilis catalyses a similar reaction in the biosynthesis of spectinabilin.
