Biochemical-Pathway Diversity in Archabacteria

摘要

A considerable extent of biochemical diversity exists in the metabolic pathways utilized in nature for the biosynthesis of aromatic amino acids and vitamin-like derivatives. The overall objective of this research is to evaluate the biochemical diversity within the archaebacteria for comparison with biochemical diversity already known or now emerging within the eubacteria. This will provide a comprehensive and rigorous sense of what aspects of diversity can be separated at the hierarchical level of the split between archaebacteria and eubacteria and it will provide a sense of which aspects of diversity are unique to each kingdom. Keywords: Biosynthesis; Aromatic compounds; Archaebacteria; Biochemical diversity; Prephenate dehydratase; Aromatic amino acid synthesis. (kt)
