  • Sulfur from Within: Cytosolic tRNA Thiouridinylation
    • Authors: Joseph J. Braymer; Dennis R. Winge
      Pages: 645 - 647
      Abstract: In this issue of Cell Chemical Biology, Pandey et al. (2018) identified that mitochondrial cysteine desulfurase provides the sulfur species used for tRNALys, tRNAGlu, and tRNAGln thiouridine modification in the cytoplasm. A low-mass sulfur species is exported by the mitochondrial Atm1 transporter and utilized in the thio-modifications.

  • Selective Inhibition of Sialic Acid-Based Molecular Mimicry in Haemophilus
           influenzae Abrogates Serum Resistance
    • Authors: Torben Heise; Jeroen D. Langereis, Emiel Rossing, Marien I. de Jonge, Gosse J. Adema, Christian Büll, Thomas J. Boltje
      Abstract: Molecular mimicry of non-typeable Haemophilus influenzae (NTHi) with host sialic acid sugars mediates resistance to serum killing and increases virulence. Heise et al. have developed sialic acid derivatives that allow either visualization or inhibition of host sialic acid transfer to NTHi, the latter enhancing serum-mediated killing.

  • A Quantitative Chemoproteomic Platform to Monitor Selenocysteine
           Reactivity within a Complex Proteome
    • Authors: Daniel W. Bak; Jinjun Gao, Chu Wang, Eranthie Weerapana
      Abstract: Bak et al. describe a chemoproteomic method for the global enrichment and identification of selenocysteine (Sec) residues. Low-pH iodoacetamide-alkyne labeling masks Cys reactivity, allowing for tissue-specific selenoprotein identification. This platform shows promise for interrogating the specificity of Sec inhibitors, such as auranofin.

  • Acyldepsipeptide Analogs Dysregulate Human Mitochondrial ClpP Protease
           Activity and Cause Apoptotic Cell Death
    • Authors: Keith S. Wong; Mark F. Mabanglo, Thiago V. Seraphim, Antonio Mollica, Yu-Qian Mao, Kamran Rizzolo, Elisa Leung, Mohamed T. Moutaoufik, Larissa Hoell, Sadhna Phanse, Jordan Goodreid, Leandro R.S. Barbosa, Carlos H.I. Ramos, Mohan Babu, Vito Mennella, Robert A. Batey, Aaron D. Schimmer, Walid A. Houry
      Abstract: Acyldepsipeptides (ADEPs) are potential antibiotics that dysregulate the activity of the highly conserved bacterial ClpP protease. We identified ADEP analogs that are potent dysregulators of the human mitochondrial ClpP (HsClpP). The compounds were found to cause apoptotic cell death. The ADEP-HsClpP co-crystal structure revealed, unexpectedly, HsClpP in the compact conformation.

      Abstract: Tilvawala et al. demonstrated that protein citrullination is elevated in RA and defined the RA-associated citrullinome. Tilvawala et al. further discovered that Serpin citrullination abolishes their ability to inhibit their cognate proteases. These studies open a new avenue to understand the links between protein citrullination and numerous diseases.

      Abstract: Koundinya et al. show that inhibitors of the pyrimidine biosynthetic enzyme dihydroorotate dehydrogenase selectively inhibit the growth of KRAS mutant cell lines. Differential sensitivity of the mutant lines correlates with differential effects of the inhibitors on primary energy metabolism and glutamine levels, and the inhibitors synergize with some clinically used anticancer agents.

  • Mitochondria Export Sulfur Species Required for Cytosolic tRNA Thiolation
    • Authors: Alok Pandey; Jayashree Pain, Nathaniel Dziuba, Ashutosh K. Pandey, Andrew Dancis, Paul A. Lindahl, Debkumar Pain
      First page: 738
      Abstract: Critical signals and metabolites move between mitochondria and cytosol, and such communications are essential for cellular homeostasis. Pandey et al. demonstrate that mitochondria generate activated sulfur intermediates (Sint). The intermediates are exported to the cytosol in an ATP-dependent fashion, and there they are utilized for thio-modification of tRNAs.
