|S-adenosyl-L-methionine + L-tryptophan <=> S-adenosyl-L-homocysteine + L-2-methyltryptophan|
- The enzyme, characterized from the bacterium Streptomyces laurentii,
is involved in thiostrepton biosynthesis.
- It is a radical SAM enzyme that contains a [4Fe-4S] center and a
- The enzyme first transfers the methyl group from SAM to the bound
cobalamin, followed by transfer from methylcobalamin to L-tryptophan,
resulting in retention of the original methyl group configuration.
- The second transfer is likely to involve a CH(3) radical species
formed from methylcobalamin by the concerted action of a partially
ligated radical SAM [4Fe-4S](2+/1+) center.
