Genes for tryptophan biosynthesis in the archaebacterium Haloferax volcanii.

Proceedings of the National Academy of Sciences of the United States of America - 1 Sept 1990

Lam W L, Cohen A, Tsouluhas D, Doolittle W F

Abstract excerpt

Recent technical advances permit direct genetic approaches for isolating genes and mapping auxotrophic mutations in the halophilic archaebacterium (Archaea) Haloferax volcanii. Twenty-nine mutations in tryptophan biosynthesis mapped to two separate chromosomal locations. DNA sequencing of one gene cluster shows a unique gene order (trpCBA) and unusual potential secondary structures in the 5'-flanking region.
