The aromatic amino acids, phenylalanine, tyrosine, and tryptophan, are formed by a reaction
sequence leading from the two carbohydrate precursors, D-erythrose 4-phosphate and …

The DNA sequence of 168 promoter regions (−; 50 to+ 10) for Escherichia coli RNA
polymerase were compiled. The complete listing was divided into two groups depending …

Dispersed repetitive DNA sequences have been described recently in eubacteria. To assess
the distribution and evolutionary conservation of two distinct prokaryotic repetitive elements …

Altered tryptophan catabolism has been identified in inflammatory diseases like rheumatoid
arthritis (RA) and spondyloarthritis (SpA), but the causal mechanisms linking tryptophan …

We describe several new vectors for the construction of operon and protein fusions to the
Escherichia colilacZ gene. In vitro constructions utilize multicopy plasmids containing …

Ribosome-mediated synthesis of proteins, us-ing messenger ribonucleic acid (mRNA) as
the template, is one of the hallmarks of earthly life forms. It is not surprising that the cellular …

Simian virus 40-based plasmids that direct the synthesis of preproinsulin during short-term
transfection of COS cells have been used to probe the mechanism of reinitiation by …

This review focuses on the gene-enzyme relationships and the regulation of different levels
of the aromatic amino acid biosynthetic pathway in a simple eukaryotic system, the …

A 4.6 kb Staphylococcus aureus DNA fragment containing DNA gyrase‐like genes (grlA and
grlB) was cloned and sequenced. The proteins GrlA and GrlB exhibit more than 30% identity …

Fos and Jun transcription factors are induced by a variety of extracellular signaling agents.
We describe here an unusual member of the Fos family that is also induced, namely, a …
