Abstract
Deuterium-labeled polyols are one of the most extensive applied chemicals in biochemistry and biophysics. However, the deuteriation still is insufficient, exhibiting a low deuterated ratio and indistinct reaction mechanism. Herein, Ru supported on MnBCD (MnBDC, derived from Mn p-phthalic acid metal-organic framework) as nanocatalyst with an agglomerated sheet-type structure; this allows the possibility of achieving both thermo- and electrocatalytic hydrogen isotope exchange (HIE) reaction. Furthermore, XPS characterization confirmed that the specific structural changes in the electron density of Ru outer layers were modulated through the impregnation and reduction processes. According to the change of outer electronic structure, hydrogen spillover and electron-rich flow promote the reaction of the catalyst in thermo- and electrocatalytic systems, respectively. In addition, the results indicate that a high deuterated ratio of 97 % can be obtained, hence the catalytic technology has enormous potential for the synthesis of a broad variety of deuterium-labeled compounds.

Molecular basis of hUHRF1 allosteric activation for synergistic histone modification binding by PI5P. SCIENCE ADVANCES 2022; 8:eabl9461. [PMID: 36001657 PMCID: PMC9401617 DOI: 10.1126/sciadv.abl9461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Accepted: 07/11/2022] [Indexed: 06/15/2023]
Abstract
Chromatin marks are recognized by distinct binding modules, many of which are embedded in multidomain proteins. How the different functionalities of such complex chromatin modulators are regulated is often unclear. Here, we delineated the interplay of the H3 amino terminus- and K9me-binding activities of the multidomain hUHRF1 protein. We show that the phosphoinositide PI5P interacts simultaneously with two distant flexible linker regions connecting distinct domains of hUHRF1. The binding is dependent on both, the polar head group, and the acyl part of the phospholipid and induces a conformational rearrangement juxtaposing the H3 amino terminus and K9me3 recognition modules of the protein. In consequence, the two features of the H3 tail are bound in a multivalent, synergistic manner. Our work highlights a previously unidentified molecular function for PI5P outside of the context of lipid mono- or bilayers and establishes a molecular paradigm for the allosteric regulation of complex, multidomain chromatin modulators by small cellular molecules.
