The principle, characteristics and recent applications of - lactam antibiotics are introduced and reviewed. moreover, the application prospects and potentiall for both strategies are evaluated
摘要介紹了在-內酰胺類抗生素酶法合成中兩大策略的原理、各自特點、目前的應用情況，並將其進行了比較，評價了各自的應用前景及開發潛力。 -
D - amino acids as unnatural chiral products are important intermediates in the synthesis of products, such as - lactam semisynthetic antibiotics, antiviral agents, artificial sweeteners, pesticide, peptide hormones, and pyrethroids, etc. though bioconversion of d - amino acids using microbial cells has been realized in industrialization for decades, some limited factors hinder the development of d - amino acid production, and ultimately result in shortage of the raw material in the related industrial fields
目前，用微生物菌體轉化生產d -型氨基酸的工藝路線已經產業化，但天然菌體轉化工藝存在一些限制因素，阻礙了d -型氨基酸的擴大生產，導致產品短缺。因此，利用基因工程菌生物轉化d -型氨基酸已成為世界氨基酸產業的新潮流。 -
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
本文將糞產堿桿菌青霉素g酰化酶（ afpga ）基因構建表達載體pkkfpga和psmlfpga ， pkkfpga和psmlfpga均含trc啟動子、青霉素g酰化酶基因、 rrnb轉錄終止子，其中pkkfpga含有氨卞青霉素抗性基因和cole1高拷貝復制子；而psmlfpga含有四環素抗性基因和p15a中拷貝復制子。
