Rational design of allosteric regulation of homoserine dehydrogenase by a nonnatural inhibitor L-lysine.

abstract：:Improved plants are necessary to meet human needs. Agrobacterium-mediated transformation is the most common method used to rewire plant capabilities. For plant gene delivery, DNA constructs are assembled into binary T-DNA vectors that rely on broad host range origins for bacterial replication. Here we present pLX vect...
