  • Title: Genes for tryptophan biosynthesis in the halophilic archaebacterium Haloferax volcanii: the trpDFEG cluster.
    Author: Lam WL, Logan SM, Doolittle WF.
    Journal: J Bacteriol; 1992 Mar; 174(5):1694-7. PubMed ID: 1537810.
    Abstract:
    Tryptophan auxotrophs of the archaebacterium Haloferax volcanii define a cluster of overlapping genes homologous to eubacterial-eukaryotic trpD, -F, -E, and -G, linked in that order and each preceded by a possible ribosome binding site. Residues involved in feedback inhibition of eubacterial anthranilate synthetases are conserved.
