The amino acid sequence of the A protein (alpha subunit) of the tryptophan synthetase of Escherichia coli.

چکیده
Tryptic digestion of the A protein (a! subunit) of the tryptophan synthetase of Escherichia coli and separation of tryptic peptides by column and paper chromatography yielded 22 nonoverlapping peptides of the total of 25 anticipated on the basis of total amino acid composition of the A protein. The amino acid composition and sequence of each purified peptide were determined. These peptides account for 213 of the total of 267 amino acid residues in the A protein.

With the plasmid DNA from a clinical isolate of enterotoxigenic Escherichia coli (ETEC) H 10407 as template, PCR-mediated cloning of the sequence encoding the heat-labile toxin B subunit (L T -B) has been carried out. Then this sequence was recloned into the pTrc 99A and pET23a expression vectors to give the pJasmids pTRCLTB and pETLTB, respectively. After induction, the former plasmid provides...
متن کاملEscherichia coli mutant trpA34 has an Asp----Asn change at active site residue 60 of the tryptophan synthetase alpha chain.
Asp-60 is believed to be a catalytically essential residue of the tryptophan synthetase alpha chain of Escherichia coli (Nagata, S., Hyde, C.C., and Miles, E.W. (1989) J. Biol. Chem. 264, 6288-6296). Surprisingly, mutations altering Asp-60 were not observed in the many trpA missense mutants characterized in the 1960s. However, there was one genetic class of trpA missense mutants, represented by...

The cDNA from the mycoparasitic fungus Trichoderma atroviride PTCC5220 encoding a 42 kDa chitinase (Chit42) was isolated. The nucleotide sequence of the cDNA fragment as having a 1263 bp open reading frame that encodes a 421 amino acid polypeptide, and a high homology was found withother reported Chit42 belonging to the Trichoderma sp. The 22 amino acid N-terminal sequence is a putative s...
متن کاملA Single Point Mutation within the Coding Sequence of Cholera Toxin B Subunit Will Increase Its Expression Yield
Background: Cholera toxin B subunit (CTB) has been extensively considered as an immunogenic and adjuvant protein, but its yield of expression is not satisfactory in many studies. The aim of this study was to compare the expression of native and mutant recombinant CTB (rCTB) in pQE vector. Methods: ctxB fragment from Vibrio cholerae O1 ATCC14035 containing the substitution of mutant ctxB for ami...
