Tryptophanase operon leader peptide; This family consists of the tryptophanase (tna) operon leader peptide. Tna catalyzes the degradation of L-tryptophan to indole, pyruvate and ammonia, enabling the bacteria to utilize tryptophan as a source of carbon, nitrogen and energy. The tna operon of E. coli contains two major structural genes, tnaA and tnaB. Preceding tnaA in the tna operon is a 319 -nucleotide transcribed regulatory region that contains the coding region for a 24-residue leader peptide, TnaC. The RNA sequence in the vicinity of the tnaC stop codon is rich in Cytidylate residues which is required for efficient Rho -dependent termination in the leader region of the tna operon. The actual alignment was detected with superfamily member PRK09806: Pssm-ID: 391796 Cd Length: 24 Bit Score: 40.04 E-value: 2.56e-07

tryptophanase leader peptide; Members of this family are the apparent leader peptides of tryptophanase operons in Esherichia coli, Vibrio cholerae, Photobacterium profundum, Haemophilus influenzae type b, and related species. All members of the seed alignment are examples ORFs upstream of tryptophanase, with a start codon, a conserved single Trp residue, and several other conserved residues. It is suggested (Konan KV and Yanofsky C) that the nascent peptide interacts with the ribosome once (if) the ribosome reaches the stop codon. Note that this model describes a much broader set (and shorter protein region) than pfam08053.
