Operon evidence: Genome analysis
Reference: Condon C, et al. (1996)
Comments: Transcriptional readthrough occurs at the stem-loop upstream of serS if uncharged serine tRNA binds to the T-box motif in the nascent mRNA transcript. The tRNA anticodon binds to the UCC codon in the sequence GAAUCCAUC in the serS leader mRNA.
