Step 1 Prepare vector

Linearize pYPKpw with EcoRV resulting in the linearized vector.

Step 2 PCR of first tp

Carry out a PCR with primers 577, 567 and template pYPKa_Z_FBA1tp resulting in the PCR product 861bp_PCR_prod

Step 5 Yeast transformation

Mix the four linear DNA fragments and transform a Saccharomyces cerevisiae ura3 mutant with the mixture. The fragments will be assembled by in-vivo homologous recombination:
