摘要：
A pectin lyase (PNL; EC 4.2.2.10) gene of Erwinia carotovora Er was cloned and expressed in Escherichia coli. The analysis of the nucleotide sequence of the 0.6 kb StuI-EcoRI fragment, which was hybridized with the mixed oligonucleotide probe for PNL gene, revealed the presence of an open reading frame (ORF) and correlated exactly with the known N-terminal 18 amino acid sequence of PNL. When a plasmid pTN2159, which has a BamHI-EcoRI fragment containing this ORF, was introduced into E. coli JM109, PNL was not expressed. When a tac-promoter was inserted in front of the ORF, PNL was efficiently expressed in E. coli. Synthesis of PNL by E. coli was also confirmed by immunoblot analysis. © 1990.
