    • This invention relates to the mutually compatible plasmids pTET3 and pCRY4, isolated from the strain of Corynebacterium glutamicum deposited under DSM number 5616, wherein plasmid pTET3 is characterised by 1.1 a length of ˜27.8 kbp and the restriction map shown in FIG. 1, 1.2 a replication region comprising the nucleotide sequence shown in SEQ ID no. 1 and 1.3 an antibiotic resistance region consisting of a tetA gene imparting tetracycline resistance and an aadA gene imparting streptomycin and spectinomycin resistance, shown in SEQ ID no. 6, and plasmid pCRY4 is characterised by 1.4 a length of ˜48 kbp and the restriction map shown in FIG. 2 and 1.5 a replication region comprising the nucleotide sequence shown in SEQ ID no. 4 to composite plasmid vectors of these plasmids which are capable of autonomous replication in coryneform bacteria and to processes for the production of L-amino acids, vitamins and nucleotides using these bacteria.
    • 本发明涉及从DSM号5616中沉积的谷氨酸棒杆菌菌株分离的相互相容的质粒pTET3和pCRY4,其中质粒pTET3的特征在于1.1,长度为约27.8kbp,图1所示的限制性图谱。 1,1.2复制区,其包含SEQ ID No: 1和1.3由SEQ ID No.3所示的赋予四环素抗性的tetA基因和赋予链霉素和壮观霉素抗性的aadA基因组成的抗生素抗性区域。 6,并且质粒pCRY4的特征在于1.4〜48kbp的长度以及图4所示的限制性图谱。 2和1.5复制区,其包含SEQ ID No: 这些质粒能够在棒状细菌中自主复制的这些质粒的复合质粒载体和使用这些细菌生产L-氨基酸,维生素和核苷酸的方法。
