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.
