Supplementary Figure 1. Alignment of the nucleotide sequences of terminal sequences.
The terminal 180 nucleotide sequences from Streptomyces chromosomes and linear plasmids are aligned. R and L indicate right and left terminal sequences of the replicon, respectively. S. avermitilis, S. coelicolor A3(2), S. lipmanii and S. parvulus are terminal sequences of the chromosomes. SLP2 and pSPA1 are the linear plasmids.




Supplementary Figure 2. Alignment of the amino acid sequences of putative terminal proteins.
TpgR1: protein sequence corresponding to the S. rochei tpgR1 gene. TpgR2: protein sequence corresponding to the S. rochei tpgR2 gene. TpgR3: protein sequence corresponding to the S. rochei tpgR3 gene. TpgL: protein sequence corresponding to the tpgL gene of S. lividans ZX7. TpgC: protein sequence corresponding to the tpgC gene of S. coelicolor A3(2). TpgA1 and TpgA2: protein sequences corresponding to the tpgA1 and tpgA2 genes of S. avermitilis on the chromosome and the linear plasmid SAP1, respectively.
