    : Loganin is an iridoid glycoside of interest as both an intermediate in the biosynthesis of indole alkaloids in plants and as a bioactive compound itself. The loganic acid methyltransferase catalyzes the methylation of a monoterpenoid glycoside precursor to produce loganin, and demonstrates stereospecificity for the (6S,7R) substrate. Here, we biochemically characterize this biocatalyst and elucidate the basis for its strict substrate specificity. These studies may help facilitate the design of new classes of monoterpenoid indole alkaloids of pharmaceutical interest.
