Critical role for uricase and xanthine dehydrogenase in soybean nitrogen fixation and nodule development

open access: yesThe Plant Genome, Volume 16, Issue 2, June 2023., 2023
Abstract De novo purine biosynthesis is required for the incorporation of fixed nitrogen in ureide exporting nodules, as formed on soybean [Glycine max (L.) Merr.] roots. However, in many cases, the enzymes involved in this pathway have been deduced strictly from genome annotations with little direct genetic evidence, such as mutant studies, to confirm

Cytochrome c signalosome in mitochondria [PDF]

open access: yes, 2011
Cytochrome c delicately tilts the balance between cell life (respiration) and cell death (apoptosis). Whereas cell life is governed by transient electron transfer interactions of cytochrome c inside the mitochondria, the cytoplasmic adducts of cytochrome

Exploring protein phosphorylation by combining computational approaches and biochemical methods

open access: yesComputational and Structural Biotechnology Journal, 2020
Post-translational modifications of proteins expand their functional diversity, regulating the response of cells to a variety of stimuli. Among these modifications, phosphorylation is the most ubiquitous and plays a prominent role in cell signaling.

Oxidative stress is tightly regulated by cytochrome c phosphorylation and respirasome factors in mitochondria [PDF]

open access: yes, 2018
Respiratory cytochrome c has been found to be phosphorylated at tyrosine 97 in the postischemic brain upon neuroprotective insulin treatment, but how such posttranslational modification affects mitochondrial metabolism is unclear.

Design of Artificial Enzymes: Insights into Protein Scaffolds

open access: yesChemBioChem, Volume 24, Issue 6, March 14, 2023., 2023
The design of artificial enzymes has emerged as a promising tool for the generation of potent biocatalysts able to promote new‐to‐nature reactions. This review aims to give a general overview of suitable protein scaffolds, that could be functionalized with an artificial moiety to develop versatile artificial catalysts. Abstract The design of artificial

Cytochrome c: Surfing Off of the Mitochondrial Membrane on the Tops of Complexes III and IV [PDF]

open access: yes, 2019
The proper arrangement of protein components within the respiratory electron transport chain is nowadays a matter of intense debate, since altering it leads to cell aging and other related pathologies.

Endothelial Glycocalyx Injury in SARS‐CoV‐2 Infection: Molecular Mechanisms and Potential Targeted Therapy

open access: yesMediators of Inflammation, Volume 2023, Issue 1, 2023., 2023
This review aims at summarizing state‐of‐the‐art knowledge on glycocalyx and SARS‐CoV‐2. The endothelial glycocalyx is a dynamic grid overlying the surface of the endothelial cell (EC) lumen and consists of membrane‐bound proteoglycans and glycoproteins.

Label-free photoacoustic microscopy of cytochromes [PDF]

open access: yes, 2013
Photoacoustic microscopy (PAM) has achieved submicron lateral resolution in showing subcellular structures; however, relatively few endogenous subcellular contrasts have so far been imaged. Given that the hemeprotein, mostly cytochromes in general cells,

Factors Controlling the Reactivity of Hydrogen Sulfide with Hemeproteins [PDF]

open access: yesBiochemistry, 2009
Hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds and transports H(2)S to sulfide-oxidizing chemoautotrophic bacteria to maintain a symbiotic relationship and to protect the mollusk from H(2)S toxicity. Single point mutations at E7, B10, and E11 were introduced into the HbI heme pocket to define the reactivity of

Insights into Sulfhemoglobin Detection: UV‐Vis and Fluorescence Spectroscopy Correlations

open access: yesJournal of Chemistry, Volume 2023, Issue 1, 2023., 2023
The mechanisms by which drugs and several sulfur chemicals induce sulfhemoglobin formation have not yet been elucidated. However, enzymes producing hydrogen sulfide in mammalian tissues and organs suggest sulfhemoglobin and sulfmyoglobin formation mechanisms are more complex than previously hypothesized. The process involves the interaction of H2S with
