Nametryptophan biosynthesis from ribose-5-phosphate
TypePATHWAY
DescriptionThe essential amino acid tryptophan is synthesized in prokaryotes, plants, and fungi via a conserved six step pathway from the branchpoint compound chrosimate, a common precursor in the biosynthesis of aromatic amino acids [1]. Seven catalytic domains and two alpha/beta subunit complexes comprise this pathway. Individually expressed in some organisms, gene fusions encoding single proteins possessing two or more of these catalytic domains have been observed for every trp gene. Although the occurance of gene fusions have been shown to be phylogenetically unrelated, a conserved gene order can be discerned within the domain Bacteria. Occasionally gene(s) dissociations disrupt gene order as in Campylobacter jejuni and Deinococcus radiodurans, or the pathway is found split between two separate chromosomes as in Rhodobacter sphaeroides. In cyanobacteria, such as Nostoc and Anabaena, it is not uncommon to observe paralogous trp genes as part of a larger "supraoperon" including other aromatic amino acid synthesizing genes as well as their trp counterparts [2].
