The gene for PUMP (putative metalloproteinase), a human matrix metalloproteinase, was synthesized by a PCR-based method. The DNA fragment of 546 bases containing the PUMP gene was generated by overlap extension of six long oligonucleotides (length ranging from 101 to 116 bases) and subsequent amplification by two short terminal oligonucleotide primers (length from 20 to 48 bases) in one pot without using restriction and ligation enzymes. The synthetic gene was cloned into a T7 expression vector in two ways to express PUMP as a non-fusion protein. Both constructs showed high level expression in E. coli.
