The complete nucleotide sequence of the cryptic plasmid pCC1 from Corynebacterium callunae (4109 bp) was determined. DNA sequence analysis revealed five open reading frames longer than 200 bp. One of the deduced polypeptides showed homology with the Rep proteins encoded by plasmids of the pIJ101/pJV1 family of plasmids replicating by the rolling-circle (RC) mechanism. Within this plasmid family, the Rep protein of pCC1 showed the highest degree of similarity to the Rep proteins of corynebacterial plasmids pAG3 and pBL1. These data suggest that the plasmid pCC1 replicates by the RC mechanism. The Escherichia coli/Corynebacterium glutamicum shuttle cloning vector pSCCD1, carrying the pCC1 rep gene on the 2.1-kb DNA fragment and the streptomycin/spectinomycin resistance determinant, was constructed. This vector is stably maintained in population of C. glutamicum cells grown in the absence of selection pressure and it is compatible with plasmid vectors based on corynebacterial plasmids pBL1 and pSR1.

D009690	Nucleic Acid Conformation	The spatial arrangement of the atoms of a nucleic acid or polynucleotide that results in its characteristic 3-dimensional shape.	DNA Conformation,RNA Conformation,Conformation, DNA,Conformation, Nucleic Acid,Conformation, RNA,Conformations, DNA,Conformations, Nucleic Acid,Conformations, RNA,DNA Conformations,Nucleic Acid Conformations,RNA Conformations
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
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.
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.

D016415	Sequence Alignment	The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.

D017124	Conserved Sequence	A sequence of amino acids in a polypeptide or of nucleotides in DNA or RNA that is similar across multiple species. A known set of conserved sequences is represented by a CONSENSUS SEQUENCE. AMINO ACID MOTIFS are often composed of conserved sequences.	Conserved Sequences,Sequence, Conserved,Sequences, Conserved

D020816	Amino Acid Motifs	Three-dimensional protein structural elements that are composed of a combination of secondary structures. They include HELIX-LOOP-HELIX MOTIFS and ZINC FINGERS. Motifs are typically the most conserved regions of PROTEIN DOMAINS and are critical for domain function. However, the same motif may occur in proteins or enzymes with different functions.
