第十二章复制子

Considering alcaligenes faecalis pencillin g acylase ( afpga ) , which possesses the attractive characteristics for beta - lactam antibiotics conversions , the gene of pga was cloned into two expressing vector pkkfpga and psmlfpga . both the constructed plasmids psmlfpga and pkkfpga contained the pga gene , trc promoter and rrnb transcript terminator , differ in the replicon and antibotic marker , pkkfpga contained multicopy replicon ( cole 1 ) and ampicillin marker . while psmlfpga contained medium - copy replicon ( p15a ) and tetracycline marker
