Journal ArticleDOI

The structure of celluloses

Masahisa Wada, +4 more
- 01 Jun 2008 - 
TL;DR: In this paper, detailed crystal structures determined for cellulose Iβ, an intermediate ammonia-cellulose I complex, and cellulose IIII, reveal a structural transition pathway: hydrogen bonded sheets of chains in celluloseIβ slip with respect to each other to accommodate the penetrating ammonia guest molecules in the intermediate complex.
Journal ArticleDOI

A coarse-grained model for synergistic action of multiple enzymes on cellulose

Andrea Asztalos, +10 more
- 01 Aug 2012 - 
TL;DR: A coarse-grained stochastic model that captures the endo-exo synergism of cellulase enzyme cocktails is presented, a critical step towards testing hypotheses and understanding approaches for maximizing synergy and substrate properties with a goal of cost effective enzymatic hydrolysis.
Journal Article

MARTINI Coarse-Grained Model for Crystalline Cellulose Microfibers B

CésarA. López, +7 more
- 01 Jan 2015 - 
TL;DR: By developing the MARTinI model of a solid cellulose crystalline fiber from the building blocks of a soluble cellobiose coarse-grained model, this work has provided a systematic way to build MARTINI models for other crystalline biopolymers.
Journal ArticleDOI

The effect of deuteration on protein structure: a high-resolution comparison of hydrogenous and perdeuterated haloalkane dehalogenase.

Xuying Liu, +3 more
- 01 Sep 2007 - 
TL;DR: The first observation of this unusual active-site configuration is obtained as a result of perdeuteration that decreases the hydrophobicity of the enzyme, therefore shifting the optimal pH of crystallization and providing an explanation for the acid inhibition of XaDHL.
Journal ArticleDOI

Protein crystallography with spallation neutrons: collecting and processing wavelength‐resolved Laue protein data

Paul Langan, +1 more
- 01 Apr 2004 - 
TL;DR: In this paper, the authors used the software suite d*TREK for data collection and processing in the protein crystallography station wavelength-resolved Laue environment, which was adapted and used in combination with the Daresbury Laue software suite, the instrument control software PCS-GUI, and the graphics program O.
