Description
A bacterial phytochrome reversibly interconverts between a parallel and antiparallel dimeric arrangement during photoconversion.
Phytochromes constitute a widespread photoreceptor family that typically interconverts between two

Red/far-red light-sensing bacteriophytochrome photoreceptor (BphP) pathways play key roles in bacterial physiology and ecology. These bilin-binding proteins photoswitch between two states, Pr (red absorbing) and Pfr (far-red absorbing). The isomeriza

Light sensing allows organisms to adapt to constantly changing environmental factors. Phytochromes constitute a widespread biological photoreceptor family that typically interconvert between two photostates called Pr (red light-absorbing) and Pfr (fa

Phytochromes are photosensitive proteins with a covalently bound open-chain chromophore that can switch between two principal states: red light absorbing Pr and far-red light absorbing Pfr. Our group has previously shown that the bacteriophytochrome

Molecular Evolution of Transition Metal Bioavailability at the Host-Pathogen Interface

Autor: Giuliano Tomás Antelo, Alejandro J. Vila, David P. Giedroc, Daiana A. Capdevila

Publikováno v: Trends Microbiol

The molecular evolution of the adaptive response at the host–pathogen interface has been frequently referred to as an 'arms race' between the host and bacterial pathogens. The innate immune system employs multiple strategies to starve microbes of m
