Hydrogen and hydration database for bio-macromolecules (HHDB)

Nourishment Essential Requirement for Bio-Hydrogen Production in Anaerobic Condition

Structural database resources for biological macromolecules

This Briefing reviews the widely used, currently active, up-to-date databases derived from the worldwide Protein Data Bank (PDB) to facilitate browsing, finding and exploring its entries. These databases contain visualization and analysis tools tailored to specific kinds of molecules and interactions, often including also complex metrics precomputed by experts or external programs, and connecti...

Hydrogen Consumption in Bio- Hydrogen Process Modelling

Fermentation of sugars for hydrogen production has received increasing interest as a “green fuel” process. Models describing products formation from sugar fermentation has been the focus, applied to generalize anaerobic digestion models. Such models have therefore been in continuous development. Beginning from fixed stoichiometry values as in ADM1 [1] (the most common platform in anaerobic dige...

Neutron Crystallography for the Study of Hydrogen Bonds in Macromolecules.

Abstract: The hydrogen bond (H bond) is one of the most important interactions that form the foundation of secondary and tertiary protein structure. Beyond holding protein structures together, H bonds are also intimately involved in solvent coordination, ligand binding, and enzyme catalysis. The H bond by definition involves the light atom, H, and it is very difficult to study directly, especia...

Neutron Protein Crystallography. Hydrogen- and Hydration-sensitive Structural Biology

Neutron protein crystallography (NPC) has not substantially contributed to the determination of the folding structures of biological macromolecules. It takes the next step beyond the folding structure of proteins. This paper demonstrates how hydrogen atoms can be seen by NPC and how NPC can explore protonation and deprotonation of amino acid residues, hydration structures, and hydrogen-to-deute...
