Transcriptional organization and genomic context of trpP and the trp operon. (A) Transcriptional organization of trpP and the l-tryptophan synthesis operon (trp operon). The arrows represent transcriptional start sites according to [34]. (B) Genomic organization of trpP-TRP in C. glutamcium and related organisms. The numbers on the right represent the percent amino acid sequence identity of the TrpP homologs to C. glutamicum TrpP according to Clustal Omega [37]. Data were taken from MicrobesOnline [38], and genes were drawn approximately to scale
