Ligands: K, PO4 Gene: aroA ("Streptomyces sviceus" Dietz in Hanka and Dietz 1973) Activity: 3-phosphoshikimate 1-carboxyvinyltransferase, with EC number 2.5.1.19 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [B5HND8_9ACTN] Catalyzes the transfer of the enolpyruvyl moiety of phosphoenolpyruvate (PEP) to the 5-hydroxyl of shikimate-3-phosphate (S3P) to produce enolpyruvyl shikimate-3-phosphate and inorganic phosphate.[HAMAP-Rule:MF_00210] Publication Abstract from PubMed Natural and modified versions of the 5-enolpyruvylshikimate-3-phosphate synthase (epsps) gene have been used to confer tolerance to the broad-spectrum herbicide glyphosate in a variety of commercial crops. The most widely utilized trait was obtained from the Agrobacterium tumefaciens strain CP4 and has been commercialized in several glyphosate-tolerant crops. The EPSPS gene products are enzymes that have been divided into three classes based on sequence similarity, sensitivity to glyphosate, and steady-state catalytic parameters. Herein, we describe the informatics-guided identification and biochemical and structural characterization of a novel EPSPS from Streptomyces sviceus (DGT-28 EPSPS). The data suggest DGT-28 EPSPS and other closely related homologues exemplify a distinct new class (Class IV) of EPSPS enzymes that display intrinsic tolerance to high concentrations of glyphosate (Ki >/= 5000 muM). We further demonstrate that dgt-28 epsps, when transformed into stable plants, provides robust (>/=4x field rates) vegetative/reproductive herbicide tolerance and has utility in weed-control systems comparable to that of commercialized events.
