Genes for tryptophan biosynthesis in the halophilic archaebacterium Haloferax volcanii: the trpDFEG cluster.

摘要

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.
