Acetonyltriphenylphosphonium nitrate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2013 Crystals of the title salt, C21H20OP+·NO3−, are composed of acetonyltriphenylphosphonium cations and nitrate anions that mainly interact through electrostatic forces. The P atom in the cation has a slightly distorted tetrahedral environment, with C—P—C angles ranging from 104.79 (7) to 112.59 (6)°. The sum of O—N—O angles of the nitrate anion is 359.99°

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Selective nitration of Hsp90 acts as a metabolic switch promoting tumor cell proliferation
Redox BiologyTumors develop in an oxidative environment characterized by peroxynitrite production and downstream protein tyrosine (Y) nitration. We showed that tyrosine nitration supports schwannoma cell proliferation and regulates cell metabolism in the inheritable ...

Sirtuin Oxidative Post-translational Modifications
Frontiers in Physiology, 2021 Increased sirtuin deacylase activity is correlated with increased lifespan and healthspan in eukaryotes. Conversely, decreased sirtuin deacylase activity is correlated with increased susceptibility to aging-related diseases.

Molecular Oncology, EarlyView.Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Engineered P450 biocatalysts show improved activity and regio-promiscuity in aromatic nitration
Scientific Reports, 2017 Nitroaromatics are among the most important and commonly used chemicals but their production often suffers from multiple unsolved challenges. We have previously described the development of biocatalytic nitration processes driven by an engineered P450 ...
