Tannic Acid-Mediated Aggregate Stabilization of Poly(N-vinylpyrrolidone)-b-poly(oligo (ethylene glycol) methyl ether methacrylate) Double Hydrophilic Block Copolymers

open access: yesNanomaterials, 2019
The self-assembly of block copolymers in aqueous solution is an important field in modern polymer science that has been extended to double hydrophilic block copolymers (DHBC) in recent years.

Glycomic analysis of high density lipoprotein shows a highly sialylated particle. [PDF]

open access: yes, 2014
Many of the functional proteins and lipids in high density lipoprotein (HDL) particles are potentially glycosylated, yet very little is known about the glycoconjugates of HDL.

A centrifugation-based physicochemical characterization method for the interaction between proteins and nanoparticles

open access: yesNature Communications, 2016
Thein vivobehaviour of nanoparticles is influenced by the presence of the protein corona. Here, the authors use analytical ultracentrifugation to study the interaction of gold nanoparticles with bovine serum albumin, to gain insight into the corona ...

Structural Characterization of Two Short Unspecific Peroxygenases: Two Different Dimeric Arrangements

open access: yesAntioxidants, 2022
Unspecific peroxygenases (UPOs) are extracellular fungal enzymes of biotechnological interest as self-sufficient (and more stable) counterparts of cytochrome P450 monooxygenases, the latter being present in most living cells.

Liquid droplet formation by HP1α suggests a role for phase separation in heterochromatin. [PDF]

open access: yes, 2017
Gene silencing by heterochromatin is proposed to occur in part as a result of the ability of heterochromatin protein 1 (HP1) proteins to spread across large regions of the genome, compact the underlying chromatin and recruit diverse ligands.

A non-classical view on calcium oxalate precipitation and the role of citrate

open access: yesNature Communications, 2017
The formation mechanism of abundant calcium oxalate biomaterials is unresolved. Here the authors show the early stages of calcium oxalate formation in pure and citrate-bearing solutions by using a titration set-up in conjunction with solution quenching ...

Nanoscale Structure Determination of Murray Valley Encephalitis and Powassan Virus Non-Coding RNAs

open access: yesViruses, 2020
Viral infections are responsible for numerous deaths worldwide. Flaviviruses, which contain RNA as their genetic material, are one of the most pathogenic families of viruses. There is an increasing amount of evidence suggesting that their 5’ and 3&#

Structure specific recognition protein-1 (SSRP1) is an elongated homodimer that binds histones [PDF]

open access: yes, 2018
The histone chaperone complex facilitates chromatin transcription (FACT) plays important roles in DNA repair, replication, and transcription. In the formation of this complex, structure-specific recognition protein-1 (SSRP1) heterodimerizes with ...

Structure of the interleukin-2 tyrosine kinase Src homology 2 domain; comparison between X-ray and NMR-derived structures [PDF]

open access: yes, 2012
The crystal structure of the interleukin-2 tyrosine kinase Src homology domain (Itk SH2) is described and it is found that unlike in studies of this domain using NMR spectroscopy, cis-trans-prolyl isomerization is not readily detected in the crystal ...

Tools for the quantitative analysis of sedimentation boundaries detected by fluorescence optical analytical ultracentrifugation. [PDF]

open access: yesPLoS ONE, 2013
Fluorescence optical detection in sedimentation velocity analytical ultracentrifugation allows the study of macromolecules at nanomolar concentrations and below. This has significant promise, for example, for the study of systems of high-affinity protein
