Dynamics of multiple lin gene expression in Sphingomonas paucimobilis B90A in response to different hexachlorocyclohexane isomers.

Sphingomonas paucimobilis B90A is able to degrade the alpha-, beta-, gamma-, and delta-isomers of hexachlorocyclohexane (HCH). It contains the genes linA, linB, linC, linD, linE, and linR, which have been implicated in HCH degradation. In this study, dynamic expression of the lin genes was measured in chemostat-grown S. paucimobilis B90A by RNA dot blot hybridization and real-time reverse trans...

Organization of lin genes and IS6100 among different strains of hexachlorocyclohexane-degrading Sphingomonas paucimobilis: evidence for horizontal gene transfer.

The organization of lin genes and IS6100 was studied in three strains of Sphingomonas paucimobilis (B90A, Sp+, and UT26) which degraded hexachlorocyclohexane (HCH) isomers but which had been isolated at different geographical locations. DNA-DNA hybridization data revealed that most of the lin genes in these strains were associated with IS6100, an insertion sequence classified in the IS6 family ...

Cloning and characterization of lin genes responsible for the degradation of Hexachlorocyclohexane isomers by Sphingomonas paucimobilis strain B90.

Hexachlorocyclohexane (HCH) has been used extensively against agricultural pests and in public health programs for the control of mosquitoes. Commercial formulations of HCH consist of a mixture of four isomers, alpha, beta, gamma, and delta. While all these isomers pose serious environmental problems, beta-HCH is more problematic due to its longer persistence in the environment. We have studied...

Posttraumatic Sphingomonas paucimobilis Endophthalmitis

A rare case of Sphingomonas paucimobilis endophthalmitis secondary to a penetrating globe injury with a retained intraocular foreign body is presented. A 30-year-old man presented with severe pain following a penetrating left eye injury. Visual acuity (VA) was 6/120. Slit-lamp examination revealed perforation of the temporal cornea and iris, hypopyon, and a fibrinous membrane covering the pupil...

Prediction of Three Dimensional Model of , Γ - Hexachlorocyclohexane Dehydrochlorinase ( Lina ) in Sphingomonas Paucimobilis Ut 26

The present study is undertaken to predict the three dimensional structure of γ-Hexachlorocyclohexane dehydrochlorinase (linA) in Sphingomonas paucimobilis UT26. γ-Hexachlorocyclohexane dehydrochlorinase (linA) catalyzes the initial steps in the biotransformation of the important insecticide γhexachlorocyclohexane (γ-HCH) by the soil bacterium Sphingomonas paucimobilisUT26. Stereo chemical anal...
