The present invention relates to a novel 5-enolpyruvylshikimate-3-phosphat-
e synthase (EPSPS). It is highly tolerant to glyphosate, the competitive
inhibitor of the substrate phosphoenolpyruvate (PEP). The invention also
relates to a gene encoding the synthase, a construct and a vector
comprising said gene, and a host cell transformed with said construct or
vector.
