  A 7-dimethylallyl tryptophan synthase from a fungal Neosartorya sp.: Biochemical characterization and structural insight into the regioselective prenylation

  摘要：

  A putative 7-dimethylallyl tryptophan synthase (DMATS) gene from a fungal Neosartorya sp. was cloned and overexpressed as a soluble His(6)-fusion protein in Escherichia coli. The enzyme was found to catalyze the prenylation of L-tryptophan at the C7 position of the indole moiety in the presence of dimethylallyl diphosphate; thus, it functions as a 7-DMATS. In this study, we describe the biochemical characterization of 7-DMATS from Neosartorya sp., referred to as 7-DMATS(Neo), and the structural basis of the regioselective prenylation of L-tryptophan at the C7 position by comparison of the three-dimensional structural models of 7-DMATS(Neo) with FgaPT2 (4-DMATS) from Aspergillus fumigatus.

  secondary metabolites including indole derivatives usually demonstrate improved biological and pharmacological activities, which make them promising candidates for drug discovery and development. The transfer reactions of a prenyl moiety from a prenyl donor, e.g. dimethylallyl diphosphate (DMAPP), to an acceptor is catalysed by prenyltransferases. One special group of such enzymes uses DMAPP and tryptophan
