The phylogenetic origin of the bifunctional tyrosine-pathway protein in the enteric lineage of bacteria.


Because bifunctional enzymes are distinctive and highly conserved products of relatively infrequent gene-fusion events, they are particularly useful markers to identify clusters of organisms at different hierarchical levels of a phylogenetic tree. Within the subdivision of gram-negative bacteria known as superfamily B, there are two distinctive types of… (More)
