| evolution of aromatic amino acid biosynthesis and application to the fine-tuned phylogenetic positioning of enteric bacteria. | a comprehensive phylogenetic tree for virtually the entire assemblage of enteric bacteria is presented. character states of aromatic amino acid biosynthesis are used as criteria, and the results are compared with partial trees based upon sequencing of 16s rrna, 5s rrna, and tryptophan leader peptide. three major clusters are apparent. enterocluster 1 possesses a gene fusion (trpg-trpd) encoding anthranilate synthase: anthranilate 5-phosphoribosylpyrophosphate phosphoribosyltransferase of tryptop ... | 1990 | 2298692 |
| extracellular oxidation of d-glucose by some members of the enterobacteriaceae. | extracellular d-glucose oxidation by 5 enterobacterial species was studied with the purpose of selecting conditions useful for taxonomic studies. extracellular production of gluconate from 14c-glucose by bacterial cells was evidenced by deae-cellulose paper chromatography. escherichia coli oxidized glucose only when pyrroloquinoline quinone (pqq) was added, whereas serratia marcescens, yersinia frederiksenii, erwinia cypripedii and cedecea lapagei oxidized d-glucose without added pqq. 2-deoxyglu ... | 1988 | 3382545 |
| 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 tyrosine-pathway dehydrogenases: (1) a broad-specificity dehydrogenase (recently termed cyclohexadienyl dehydrogenase [cdh]) that can utilize ei ... | 1988 | 3386529 |
