Figure 4From: Prediction of Sinorhizobium meliloti sRNA genes and experimental detection in strain 2011Summary of the scoring criteria introduced to weigh the relative position of predicted transcriptional signals in IgRs. An IgR with a co-oriented putative promoter and a terminator separated from by 40–500 bp each other was scored 10. Every promoter-terminator pair matching the previous criterion within a single IgR was rated individually and summed to calculate the global score of that IgR. Orphan promoters were scored 3. Putative promoters were rated 2 if the 5'-end of the co-oriented flanking CDS was farther than 300 bp, 1 if this distance was 200–300 bp and 0, if they were closer than 200 bp. Orphan terminators were scored 3. Predicted terminators co-oriented with flanking ORFs were scored according to their relative distance to the 3'-end of the corresponding annotated gene, so that a score of 2 was assigned if the terminator was farther than 200 bp, 1 if the distance was 100–200 nt, and 0 if it was closer than 100 bp.Back to article page
