Serine is a new target residue for endogenous ADP-ribosylation on histones

October 10th, 2016 by Orsolya Leidecker

Nature Chemical Biology 12, 998 (2016). doi:10.1038/nchembio.2180

Authors: Orsolya Leidecker, Juan José Bonfiglio, Thomas Colby, Qi Zhang, Ilian Atanassov, Roko Zaja, Luca Palazzo, Anna Stockum, Ivan Ahel & Ivan Matic

ADP-ribosylation (ADPr) is a biologically and clinically important post-translational modification, but little is known about the amino acids it targets on cellular proteins. Here we present a proteomic approach for direct in vivo identification and quantification of ADPr sites on histones. We have identified 12 unique ADPr sites in human osteosarcoma cells and report serine ADPr as a new type of histone mark that responds to DNA damage.

Cbr1 is a Dph3 reductase required for the tRNA wobble uridine modification

October 3rd, 2016 by Zhewang Lin

Nature Chemical Biology 12, 995 (2016). doi:10.1038/nchembio.2190

Authors: Zhewang Lin, Min Dong, Yugang Zhang, Eunyoung Alisa Lee & Hening Lin

Diphthamide and the tRNA wobble uridine modifications both require diphthamide biosynthesis 3 (Dph3) protein as an electron donor for the iron-sulfur clusters in their biosynthetic enzymes. Here, using a proteomic approach, we identified Saccharomyces cerevisiae cytochrome b5 reductase (Cbr1) as a NADH-dependent reductase for Dph3. The NADH- and Cbr1-dependent reduction of Dph3 may provide a regulatory linkage between cellular metabolic state and protein translation.
