In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Design of optimal Earth pole-sitter transfers using low-thrust propulsion [PDF]

, 2012
Recent studies have shown the feasibility of an Earth pole-sitter mission using low-thrust propulsion. This mission concept involves a spacecraft following the Earth's polar axis to have a continuous, hemispherical view of one of the Earth's poles.

Effect of service temperature on cyclic mechanical behavior of magnesium with fine grained structure

Journal of Materials Research and Technology
To explore the effect of operational service temperatures on the fatigue properties of fine-grained magnesium, we processed magnesium using multi-pass rolling at about 200oC and then tested the samples under a cyclic tension-tension loading at various ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Papillary renal adenoma in a toco toucan (Ramphastos toco)

Brazilian Journal of Veterinary Pathology, 2018
Primary renal neoplasms are infrequent in domestic animals and birds, being budgerigars an exception. This report describes a papillary renal adenoma in a toco toucan (Ramphastos toco), which was euthanized due to poor prognosis after surgical ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Trajectory and spacecraft design for a pole-sitter mission [PDF]

, 2014
This paper provides a detailed mission analysis and systems design of a pole-sitter mission. It considers a spacecraft that is continuously above either the North or South Pole and, as such, can provide real-time, continuous and hemispherical coverage of

Moment Pole Figures in Residual Stress Analysis [PDF]

Texture, Stress, and Microstructure, 1996
The basic formulas (Reuss′s approximation) for residual stress analysis are given in a revised form. All ODF‐burdened information reduces to five “moment pole figures” simply to, calculate using modern direct algorithms. The corresponding harmonic expressions are also more compact than other formulas known from literature.

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

FEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...
