Other name(s): | sesA (gene name) | ||
Systematic name: | (+)-sesamin:tetrahydrofolate N-methylenetransferase | ||
Comments: | This enzyme was characterized from the bacterium Sinomonas sp. No.22. It catalyses a cleavage of a methylene bridge, followed by the transfer of the methylene group to tetrahydrofolate. The enzyme is also active with (+)-episesamin, (–)-asarinin, (+)-sesaminol, (+)-sesamolin, and piperine. | ||
