H/D exchange kinetics at the level of the amide proton in the mid infrared (1700-1500 cm(-1)) make it possible to study the conformational flexibility of membrane proteins, independent of size or the presence of detergent or lipids. Slow, medium, and

Protein localization mechanisms dictate the functional and structural specialization of cells. Of the four polar surface organelles featured by the dimorphic bacterium Caulobacter crescentus , the stalk, a cylindrical extension of all cell envelope l

Hydrogen peroxide features in many biological oxidative processes and must be continuously degraded enzymatically either via a catalatic or a peroxidatic mechanism. For this purpose ancestral bacteria evolved a battery of different heme and non-heme

Probing flagellar promoter occupancy in wild-type and mutant Caulobacter crescentus by chromatin immunoprecipitation

Autor: Davis, Nicole J., Viollier, Patrick H.

Publikováno v: FEMS Microbiology Letters, Vol. 319, No 2 (2011) pp. 146-52

In the asymmetric predivisional cell of Caulobacter crescentus, TipF and TipN mark the cellular pole for future flagellar development. TipF is essential for motility and contains a cyclic-di-GMP phosphodiesterase-like (EAL) domain that is necessary f

Vitamin B6 is essential in all organisms, due to its requirement as a cofactor in the form of pyridoxal 5′-phosphate (PLP) for key metabolic enzymes. It can be synthesized de novo by either of two pathways known as deoxyxylulose 5-phosphate (DXP)-d
