recommendations! Published in 2024 at "Journal of Proteome Research"

DOI: 10.1021/acs.jproteome.4c00466

Abstract: The transition from planktonic to biofilm growth in bacteria is often accompanied by greater resistance to antibiotics and other stressors, as well as distinct alterations in physical traits, genetic activity, and metabolic restructuring. In many… read more here.

DOI: 10.1073/pnas.2003163117

Abstract: Significance F-ATP synthase is a fundamental enzyme supplying adenosine triphosphate (ATP), spreading across all kingdoms of life. Despite remarkable conservation of its basic structure and function, biophysical studies have revealed discrete differences in the rotary… read more here.

DOI: 10.1111/1462-2920.70079

Abstract: In denitrifying bacteria, nitric oxide (NO) is an electron acceptor and a free intermediate produced during anaerobic respiration. NO is also a signal for transcriptional regulation of the genes encoding nitrite (Nir), nitric oxide (Nor)… read more here.

DOI: 10.1111/1758-2229.12674

Abstract: Many gram-negative bacteria utilize N-acyl homoserine lactone (AHL) signals to communicate with each other. Once they have been released, these signals are assumed to be shared among the population in the local environment. In contrast… read more here.

DOI: 10.1128/jb.00027-23

Abstract: Paracoccus denitrificans is a metabolically versatile Gram-negative bacterium that is used as a model for studies of respiratory metabolism. The organism can utilize nitrate as an electron acceptor for anaerobic respiration, reducing it to dinitrogen… read more here.

DOI: 10.1128/spectrum.03811-23

Abstract: ABSTRACT In the nitrogen biogeochemical cycle, the reduction of nitrous oxide (N2O) to N2 by N2O reductase, which is encoded by nosZ gene, is the only biological pathway for N2O consumption. In this study, we… read more here.

DOI: 10.3389/fmolb.2025.1679650

Abstract: Heme-nitric oxide/oxygen binding (H-NOX) proteins function as critical sensors for nitric oxide in many bacterial species. However, their physiological functions are surprisingly diverse, and most have yet to be thoroughly investigated. Here, we investigate the… read more here.

DOI: 10.3390/antiox11050902

Abstract: Paracoccus denitrificans ArsH is encoded by two identical genes located in two distinct putative arsenic resistance (ars) operons. Escherichia coli-produced recombinant N-His6-ArsH was characterized both structurally and kinetically. The X-ray structure of ArsH revealed a… read more here.
