dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Oyster Shell Proteins Originate from Multiple Organs and Their Probable Transport Pathway to the Shell Formation Front. [PDF]

PLoS ONE, 2013
Mollusk shell is one kind of potential biomaterial, but its vague mineralization mechanism hinders its further application. Mollusk shell matrix proteins are important functional components that are embedded in the shell, which play important roles in ...

Unified Model of Radio and X-Ray Emission of Nova CI Cam 1998

, 2010
A unified model is proposed for the radio and X-ray outburst of nova CI Cam 1998 which suggests the shock interaction of nova shell with the circumstellar gas.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Systematic trends in the spin-orbit splitting toward weak-binding

Frontiers in Physics
Spin–orbital (SO) splitting in atomic nuclei results from the coupling between a nucleon’s spin and its orbital angular momentum, fundamentally influencing nuclear structure, especially near the magic numbers.

Study on acoustic vibration similarity law of complex stiffened cone-cylinder combined shell

Zhongguo Jianchuan Yanjiu, 2022
ObjectiveDue to the difficulty of accurately converting the experimental results of acoustic radiation and vibration from scale models of complex stiffened combined shells into prototypes, the acoustic vibration similarity laws of this type of combined ...

Back Reaction of Hawking Radiation on Black Hole Geometry

, 1997
We propose a model for the geometry of a dynamical spherical shell in which the metric is asymptotically Schwarzschild, but deviates from Ricci-flatness in a finite neighbourhood of the shell. Hence, the geometry corresponds to a `hairy' black hole, with

Triaxial projected shell model approach [PDF]

, 1998
The projected shell model analysis is carried out using the triaxial Nilsson+BCS basis. It is demonstrated that, for an accurate description of the moments of inertia in the transitional region, it is necessary to take the triaxiality into account and ...
