DOI: 10.1016/j.bbrc.2021.02.090

Abstract: Chemotaxis is the process of sensing chemical gradients and navigating towards favourable conditions. Bacterial chemotaxis is mediated by arrays of trans-membrane chemoreceptor proteins. The most common class of chemoreceptors have periplasmic ligand-binding domains (LBDs) that… read more here.

DOI: 10.1038/s41467-024-45500-y

Abstract: Chemoreception – the ability to smell and taste – is an essential sensory modality of most animals. The number and type of chemical stimuli that animals can perceive depends primarily on the diversity of chemoreceptors… read more here.

DOI: 10.1039/c7dt03802j

Abstract: A dual-channel chromogenic and fluorogenic fused-aromatic-system-based chemoreceptor (2-(benzo[d]thiazol-2-yl)-1-((pyren-8-yl)methylene)hydrazine) (TyM) was designed for ditopic sensitivity towards heavy and transition metal ions (HTMs), such as Cu2+, in an aqueous medium and lethal CN- in a semi-aqueous medium.… read more here.

DOI: 10.1073/pnas.2204161119

Abstract: Significance The conformational changes that accompany signaling events in transmembrane chemoreceptors are difficult to follow with structural methods that cannot replicate the native cellular environment. We developed in vivo cysteine crosslinking reporters of the Escherichia… read more here.

DOI: 10.1111/1755-0998.13471

Abstract: We present the chromosome-level genome assembly of Dysdera silvatica Schmidt, 1981, a nocturnal ground-dwelling spider endemic from the Canary Islands. The genus Dysdera has undergone a remarkable diversification in this archipelago mostly associated with shifts… read more here.

DOI: 10.1111/mmi.15007

Abstract: The marine pathogen Vibrio vulnificus senses and responds to environmental stimuli via two chemosensory systems and 42–53 chemoreceptors. Here, we present an analysis of the V. vulnificus Aer2 chemoreceptor, VvAer2, which is the first V.… read more here.

DOI: 10.1128/jb.00027-22

Abstract: Bodhankar et al. reported a noncanonical sensing mechanism that involves signal interaction with the McpA chemoreceptor signaling domain resulting in a chemorepellence response of Bacillus subtilis. The identified repellent binding site is analogous to that… read more here.

DOI: 10.1128/mbio.00973-19

Abstract: In Escherichia coli, membrane-bound chemoreceptors, the histidine kinase CheA, and coupling protein CheW form highly ordered chemosensory arrays. In core signaling complexes, chemoreceptor trimers of dimers undergo conformational changes, induced by ligand binding and sensory… read more here.

DOI: 10.1186/s13059-025-03703-6

Abstract: Plant pathogens and plant-associated bacteria contain about twice as many chemoreceptors as the bacterial average, indicating that chemotaxis is particularly important for bacteria-plant interactions. However, information on the corresponding chemoreceptors is limited. In this study,… read more here.
