Description
Coding region for PyrF gene. PyrF is used in the synthesis of uracil in the same pathway that Ura3 is used in yeast. Can also be used as a conterselectable marker in the presence of 5-Fluoroorotic Acid (5-FOA) and the absence of uracil.
Notes
Four silent mutations were introduced to eliminate EcoRI and PstI restriction enzyme sites. The EcoRI site was eliminated at base 39 with a G -> A mutation. PstI sites were eliminated at 240 and and 441 with T -> C mutations, and at 261 with a T -> G mutation. Mutation choices were selected to match codons with similar codon usage.
