Novel cloning vectors for glutamic acid-producing bacteria have been constructed. Two cryptic plasmids, pAM330 from Brevibacterium lactofermentum and pHM1519 from Corynebacterium glutamicum, were used as precursors, and recombined with pBR325 or pUB110. Resultant composite plasmids were able to propagate and to express the CmR or KmR phenotype in B. lactofermentum and C. glutamicum. A smaller, high-copy-number plasmid, pAJ43, was also isolated following deletion of a part of the pAM330-pBR325 composite plasmid. Furthermore, a cosmid vector, which can be packaged and transduced through phage infection, has been developed using a cohesive-end fragment of the f1A phage and plasmid pAJ43. These plasmids are suitable for use as cloning vectors in the glutamic acid-producing bacteria.

UI MeSH Term Description Entries
D010957 Plasmids Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS. Episomes,Episome,Plasmid
D001951 Brevibacterium A gram-positive organism found in dairy products, fresh and salt water, marine organisms, insects, and decaying organic matter.
D002874 Chromosome Mapping Any method used for determining the location of and relative distances between genes on a chromosome. Gene Mapping,Linkage Mapping,Genome Mapping,Chromosome Mappings,Gene Mappings,Genome Mappings,Linkage Mappings,Mapping, Chromosome,Mapping, Gene,Mapping, Genome,Mapping, Linkage,Mappings, Chromosome,Mappings, Gene,Mappings, Genome,Mappings, Linkage
D003352 Corynebacterium A genus of asporogenous bacteria that is widely distributed in nature. Its organisms appear as straight to slightly curved rods and are known to be human and animal parasites and pathogens.
D003360 Cosmids Plasmids containing at least one cos (cohesive-end site) of PHAGE LAMBDA. They are used as cloning vehicles. Cosmid
D005822 Genetic Vectors DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

D005971 Glutamates Derivatives of GLUTAMIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the 2-aminopentanedioic acid structure. Glutamic Acid Derivatives,Glutamic Acids,Glutaminic Acids
D014161 Transduction, Genetic The transfer of bacterial DNA by phages from an infected bacterium to another bacterium. This also refers to the transfer of genes into eukaryotic cells by viruses. This naturally occurring process is routinely employed as a GENE TRANSFER TECHNIQUE. Genetic Transduction,Genetic Transductions,Transductions, Genetic
