Identification and characterization of a pSLA2 plasmid locus required for linear DNA replication and circular plasmid stable inheritance in Streptomyces lividans.
Streptomyces linear plasmids and linear chromosomes can replicate also in a circular form when their telomeres are deleted. The 17-kb linear plasmid pSLA2 has been a useful model in studies of such replicons. Here we report that the minimal origin initiating replication of pSLA2-derived plasmids as circular molecules cannot propagate these plasmids in a linear mode unless they also contain a no...
متن کاملCharacterization of the genetic components of Streptomyces lividans linear plasmid SLP2 for replication in circular and linear modes.
The nucleotide sequence of Streptomyces lividans linear plasmid SLP2 consists of 50,410 bp (C. H. Huang, C. Y. Chen, H. H. Tsai, C. Chen, Y. S. Lin, and C. W. Chen, Mol. Microbiol. 47:1563-1576, 2003). Here we report that the basic SLP2 locus for plasmid replication in circular mode resembles that of Streptomyces linear plasmids pSLA2 and SCP1 and comprises iterons(SLP2) and the adjacent rep(SL...
متن کاملComplementation of conjugation functions of Streptomyces lividans plasmid pIJ101 by the related Streptomyces plasmid pSB24.2.
A database search revealed extensive sequence similarity between Streptomyces lividans plasmid pIJ101 and Streptomyces plasmid pSB24. 2, which is a deletion derivative of Streptomyces cyanogenus plasmid pSB24.1. The high degree of relatedness between the two plasmids allowed the construction of a genetic map of pSB24.2, consisting of putative transfer and replication loci. Two pSB24.2 loci, nam...
متن کاملCharacterization of the replication, transfer, and plasmid/lytic phage cycle of the Streptomyces plasmid-phage pZL12.
We report here the isolation and recombinational cloning of a large plasmid, pZL12, from endophytic Streptomyces sp. 9R-2. pZL12 comprises 90,435 bp, encoding 112 genes, 30 of which are organized in a large operon resembling bacteriophage genes. A replication locus (repA) and a conjugal transfer locus (traA-traC) were identified in pZL12. Surprisingly, the supernatant of a 9R-2 liquid culture c...
