5-Fluoroindole resistance identifies tryptophan synthase beta subunit mutants in Arabidopsis thaliana.
A study of the biochemical genetics of the Arabidopsis thaliana tryptophan synthase beta subunit was initiated by characterization of mutants resistant to the inhibitor 5-fluoroindole. Thirteen recessive mutations were recovered that are allelic to trp2-1, a mutation in the more highly expressed of duplicate tryptophan synthase beta subunit genes (TSB1). Ten of these mutations (trp2-2 through t...
متن کاملTwo anthranilate synthase genes in Arabidopsis: defense-related regulation of the tryptophan pathway.
Arabidopsis thaliana has two genes, ASA1 and ASA2, encoding the alpha subunit of anthranilate synthase, the enzyme catalyzing the first reaction in the tryptophan biosynthetic pathway. As a branchpoint enzyme in aromatic amino acid biosynthesis, anthranilate synthase has an important regulatory role. The sequences of the plant genes are homologous to their microbial counterparts. Both predicted...
متن کاملCloning and Sequencing of Bacillus stearothermophilus Tryptophan Synthase Genes
The tryptophan synthase genes, trpA and trpB, of Bacillus stearothermophilus IFO13737 were cloned by transformation of tryptophan auxotrophic mutations of the trp genes into Escherichia coli. The genes are located in the order of trpB and tipA, according to their coding orientation, in a 2.5 kb EcoKV-Hindlll DNAfragment. The complete nucleotide sequence of this DNAwas determined. The tipA and t...
متن کاملProduction of a novel tryptophan analog, beta-1-indazole-L-alanine with tryptophan synthase of Escherichia coli.
The tryptophan synthase alpha 2 beta 2 complex from Escherichia coli has been found to catalyze the beta-replacement reaction of L-serine with indazole, an indole analog which has a nitrogen atom at the 2-position (pyrazole ring). The reaction product was isolated and identified as beta-indazolealanine by mass spectrometric, elemental and NMR analyses. Careful assignment of 1H- and 13C-signals ...
متن کاملSubunit of Tryptophan Synthase with Strong Homology to the trpB Genes of Arabidopsis and Maize (Zea mays
We report the sequence of the frpS gene of the cyanobaderium Synechocysfis sp. PCC 6803. This gene was cloned from a plasmid library by functional complementation of a frpS mutant of Escherichia coli K-12. Among the known frpS sequences, the Synechocysfis gene bears the greatest homology to the duplicated frpS genes of Arabidopsis thaliana and Zea mays. Southern and northern blotting analyses s...
