Abstract
Cloning and characterization of 5-enopyruvylshikimate-3-phosphate synthase from Pantoea sp
Author(s): F. Liu and Y.P. CaoThe shikimate pathway enzyme 5-enopyruvylshikimate-3-phosphate synthase (EPSPS) is the target of the broad spectrum herbicide glyphosate. A novel aroA gene encoding an EPSPS from Pantoea sp was identified and subcloned into the pET-28a vector to construct the recombinant pET-AroAPantoea sp plasmid. Amino acid sequence analysis indicated that AroAPantoea sp is a class I AroA enzyme. When expressed in Escherichia coli, it conveyed high tolerance to glyphosate. AroAPantoea sp may be used to generate transgenic glyphosate-tolerant plants.
