L-tyrosine regulation and biosynthesis via arogenate dehydrogenase in suspension-cultured cells of Nicotiana silvestris Speg. et Comes
The biosynthetic route to L-tyrosine was identified in isogenic suspension-cultured cells of N. silvestris. Arogenate (NADP+) dehydrogenase, the essential enzyme responsible for the conversion ofExpand

Biosynthesis of phenazine pigments in mutant and wild-type cultures of Pseudomonas aeruginosa.
Pigmentation mutants of Pseudomonas aeruginosa, selected by observed visual differences in coloration from the wild-type strain, were examined for altered patterns of phenazine synthesis. ThreeExpand

Variable enzymological patterning in tyrosine biosynthesis as a means of determining natural relatedness among the Pseudomonadaceae.
Enzymes of tyrosine biosynthesis (prephenate dehydrogenase and arogenate dehydrogenase) were characterized in 90 species currently classified within the genera Pseudomonas, Xanthomonas, andExpand

The aromatic amino acid pathway branches at L-arogenate in Euglena gracilis.
The recently characterized amino acid L-arogenate (Zamir et al., J. Am. Chem. Soc. 102:4499-4504, 1980) may be a precursor of either L-phenylalanine or L-tyrosine in nature. Euglena gracilis is theExpand

Biotransformations of the cardiovascular drugs mexrenone and canrenone.
Microbial transformation studies of the cardiovascular drugs mexrenone (1) and canrenone (2) were conducted. Thirty-nine biotransformations of mexrenone and 84 biotransformations of canrenone wereExpand

Diverse enzymological patterns of phenylalanine biosynthesis in pseudomonads are conserved in parallel with deoxyribonucleic acid homology groupings.
l-Tyrosine biosynthesis in nature has proven to be an exceedingly diverse gestalt of variable biochemical routing, cofactor specificity of pathway dehydrogenases, and regulation. A detailed analysisExpand

Comparative allostery of 3-deoxy-D-arabino-heptulosonate 7-phosphate synthetase as an indicator of taxonomic relatedness in pseudomonad genera.
Recently, an analysis of the enzymological patterning of L-tyrosine biosynthesis was shown to distinguish five taxonomic groupings among species currently named Pseudomonas, Xanthomonas, orExpand
