Pseudomonas putida Tryptophan Synthetase : Partial Sequence of the a Subunit IRVING
There is 50% identity in the sequences of the first 50 residues of the a chains of Escherichia coli and Pseudomonas putida. No deletions or additions of residues are found in this region, except for the N-terminal methionine residue which is missing in the polypeptide isolated from P. putida. Most of the residues which differ are chemically dissimilar, and half of them are specified by codons w...
متن کاملFine structure mapping of the tryptophan genes in Pseudomonas putida.
ave used the tryptophan pathway to develop a gene transfer system via wta:sducing bacteriophage in Pseudomonas putida ( CHAKRAEARTY, GUNSALUS and GUNSALUS 1967). The tryptophan pathway itself has proved interesting in the number and nature of its enzymes, their mode of regulation, and the organization of the genes in the bacterial chromosome. Enzymatic analysis of extracts of prototrophic and a...
متن کاملTryptophan Synthetase ,& Subunit
Radioactivity incorporated into an e-N-5’-phosphopyridoxyllysine residue of the /3 chain by reduction of the flZ holoenzyme with tritiated sodium borohydride appears in two tryptic peptides. These pyridoxyl peptides differ by only a single arginyl residue. As expected, tryptic digests of normal protein contain two peptides that together make up the pyridoxyl peptide region. The primary structur...

Received: 21 April, 2009 Accepted: 8 July, 2009 Abstract Background & Aims: Dimethoate as an organophosphorus compound is commonly used for crop production which is neurotoxic in human. Pseudomonas family harbor organophosphate degrading plasmids have been known as tools for cleaning environmental pollutions. Materials & Methods: Pseudomonas Putida was isolated from contaminated soil b...
متن کاملTryptophan Synthetase Activity in Pea Seedling Extracts.
Extracts of several microorganisms have been shown to possess tryptophan synthetase activity (2, 5, 6, 8, 9), i.e., such preparations, when incubated in buffer in the presence of indole, serine, and pyridoxal phosphate, catalyze a condensation of indole and serine with the concomitant production of an equivalent amount of tryptophan. Animals, which have a dietary requirement for tryptophan, app...
