The ColR-ColS two-component signal transduction system is involved in regulation of Tn4652 transposition in Pseudomonas putida under starvation conditions

Involvement of s in Starvation-Induced Transposition of Pseudomonas putida Transposon Tn4652

The ColRS two-component system regulates membrane functions and protects Pseudomonas putida against phenol.

As reported, the two-component system ColRS is involved in two completely different processes. It facilitates the root colonization ability of Pseudomonas fluorescens and is necessary for the Tn4652 transposition-dependent accumulation of phenol-utilizing mutants in Pseudomonas putida. To determine the role of the ColRS system in P. putida, we searched for target genes of response regulator Col...

Cross-regulation between a novel two-component signal transduction system for catabolism of toluene in Pseudomonas mendocina and the TodST system from Pseudomonas putida.

The tmoABCDEF genes encode the toluene-4-monooxygenase from Pseudomonas mendocina KR1. Upstream from the tmoA gene an open reading frame, tmoX, encoding a protein 83% identical to TodX (todX being the initial gene in the todXFC1C2BADEGIH operon from Pseudomonas putida DOT-T1E) was found. The tmoX gene is also the initial gene in the tmoXABCDEF gene cluster. The transcription initiation point fr...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

A two-component hydroxylase involved in the assimilation of 3-hydroxyphenyl acetate in Pseudomonas putida.

The complete catabolic pathway involved in the assimilation of 3-hydroxyphenylacetic acid (3-OH-PhAc) in Pseudomonas putida U has been established. This pathway is integrated by the following: (i) a specific route (upper pathway), which catalyzes the conversion of 3-OH-PhAc into 2,5-dihydroxyphenylacetic acid (2,5-diOH-PhAc) (homogentisic acid, Hmg), and (ii) a central route (convergent route),...
