title: [Enhanced prokaryotic expression of a recombinant Lagurus lagurus zona pellucida subunit 3 with codon optimization].
abstract: OBJECTIVE
  To improve prokaryotic expression level of Lagurus lagurus zona pellucida 3(LZP3) gene.
  
  
  METHODS
  The rare codons of LZP3 gene fragment were turned into the most frequently used codons in E. coli by overlap PCR. LZP3 gene and mutated LZP3 (LZP3m) gene were cloned into expression vector pGEX4T-1 respectively, and transformed into E. coli BL21(DE3).
  
  
  RESULTS
  The expression level of LZP3m was notably higher than that of LZP3.
  
  
  CONCLUSIONS
  The expression of LZP3 gene in E. coli could be successfully improved by using codon optimization.
