Structure of E3 ligase E6AP with a proteasome-binding site provided by substrate receptor hRpn10

open access: yesNature Communications, 2020
Human ubiquitin E3 ligase E6AP contains a Zn-binding AZUL domain. Here the authors identify and name RAZUL, a domain in proteasome substrate receptor hRpn10 that binds AZUL, recruiting E6AP to proteasomes, and they present the NMR structure of the RAZUL ...

Structure-guided bifunctional molecules hit a DEUBAD-lacking hRpn13 species upregulated in multiple myeloma

open access: yesNature Communications, 2021
Rpn13 is a substrate receptor of the 26S proteasome and an anti-cancer drug target. Here, the authors identify and characterize XL5, a lead compound that binds to the N-terminal Pru domain of human Rpn13 (hRpn13), solve the NMR structure of XL5-ligated ...

Characterizing polygonality in biological structures [PDF]

open access: yesPhysical Review E, 2006
Several systems involve spatial arrangements of elements such as molecules or cells, the characterization of which bears important implications to biological and physical investigations. Traditional approaches to quantify spatial order and regularity have relied on nearest neighbor distances or the number of sides of cells.

A combined evolutionary and structural approach to disclose the primary structural determinants essential for proneurotrophins biological functions

open access: yesComputational and Structural Biotechnology Journal, 2021
The neurotrophins, i.e., Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF), Neurotrophin 3 (NT3) and Neurotrophin 4 (NT4), are known to play a range of crucial functions in the developing and adult peripheral and central nervous systems.

A Structural Characterization of Human SCO2 [PDF]

open access: yesStructure, 2007
Human Sco2 is a mitochondrial membrane-bound protein involved in copper supply for the assembly of cytochrome c oxidase in eukaryotes. Its precise action is not yet understood. We report here a structural and dynamic characterization by NMR of the apo and copper(I) forms of the soluble fragment.

Processing and characterization of CaTiO3 perovskite ceramics [PDF]

open access: yesProcessing and Application of Ceramics, 2014
Calcium titanate (CaTiO3) ceramics with perovskite structure were produced by solid state reaction. Calcium carbonate (CaCO3) and titanium dioxide (TiO2) were mixed (in molar ratios 1/1 and 3/2), and the obtained mixtures were calcined at 1150 °C in ...
