摘要

Two closely related subgroups of group I pseudomonads, which differ from one another in the overall enzymatic makeup of aromatic amino acid biosynthesis, possess in common the recently characterized major (tyrosine-sensitive) and minor (tryptophan-sensitive) isozymes of 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase of Pseudomonas aeruginosa (17). Since these characterizations were made for strains whose phylogenetic positions have been determined by oligonucleotide cataloging, an initial perception of the evolution of aromatic pathway construction and regulation is emerging.
