pSCL2 (120 kb), one of the linear plasmids found in Streptomyces clavuligerus NRRL3585, was isolated and partially sequenced. Computational analysis of the central region of pSCL2 revealed the presence of two open reading frames that appear to encode proteins highly homologous to RepL1 and RepL2, replication proteins from pSLA2-L, the large linear plasmid in Streptomyces rochei. The S. clavuligerus open reading frames were designated repC1 and repC2, encoding the proteins RepC1 (150 amino acids) and RepC2 (102 amino acids), respectively. The RepC and RepL proteins have identical translation features and very similar predicted secondary and tertiary structures. Functional analysis confirmed that RepC1 is essential for replication initiation of pSCL2, whereas RepC2 is dispensable but may play a role in copy number control. The RepC and RepL proteins do not show similarity to any other bacterial plasmid replication proteins. Three regions of DNA sequence, Box 1 (1050–850 bp), Box 2 (723–606 bp), and Box 3 (224–168 bp), located upstream of repC1, were also shown to be essential or very important for replication of pSCL2.Key words: pSCL2, Streptomyces clavuligerus, replication origin.

The DNA sequencing and preliminary functional analysis of a 32 kb section of yeast chromosome I has been completed. This region lies on the left arm of the chromosome between the LTE1 and SPO7 genes and contains 14 open reading frames (ORFs) positioned closely together, with an average spacing of approximately 350 nucleotides between coding regions. Three of these ORFs correspond to previously identified genes, a further three show significant homology with other proteins, while the remaining eight ORFs share no significant homology to genes in the databases.Key words: chromosome I, genome analysis, Saccharomyces cerevisiae, yeast.

ABSTRACT A gene cluster composed of nine open reading frames (ORFs) involved in Ni2+, Co2+, and Zn2+ sensing and tolerance in the cyanobacterium Synechocystis sp. strain PCC 6803 has been identified. The cluster includes an Ni2+response operon and a Co2+ response system, as well as a Zn2+ response system previously described. Expression of the Ni2+ response operon (nrs) was induced in the presence of Ni2+ and Co2+. Reduced Ni2+ tolerance was observed following disruption of two ORFs of the operon (nrsA and nrsD). We also show that the nrsD gene encodes a putative Ni2+ permease whose carboxy-terminal region is a metal binding domain. The Co2+ response system is composed of two divergently transcribed genes, corR and corT, mutants of which showed decreased Co2+ tolerance. Additionally, corR mutants showed an absence of Co2+-dependent induction of corT, indicating that CorR is a transcriptional activator of corT. To our knowledge, CorR is the first Co2+-sensing transcription factor described. Our data suggest that this region of theSynechocystis sp. strain PCC 6803 genome is involved in sensing and homeostasis of Ni2+, Co2+, and Zn2+.
