Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

AbstractFor numerically solving PDEs, node or grid adaptation schemes have been invented, applied, and improved mainly to improve solution accuracy while reducing the burden caused by CPU-limitation and/or users’ interference. This becomes crucial particularly for problems involving strong changes in physical phenomena.

Abstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.

Circular thin plates buckling analysis with HRPIM method [PDF]
This paper aims to introduce a new approach to simulate geometrically nonlinear problems that require shape functions with higher order continuity such as the buckling analysis of circular thin and thick plates based on two theories; Classical plate ...

Structural and functional specialization of Bordetella pertussis DsbA for pertussis toxin folding
Abstract Disulphide bonds (Dsbs) are essential for the folding, stability, and function of many secreted and membrane‐associated proteins in bacteria. In Gram‐negative species, these bonds are introduced by the Dsb enzyme family, with DsbA acting as the primary thiol oxidase.

The structural and biochemical impacts of monomerizing human acetylcholinesterase
Abstract Serving a critical role in neurotransmission, human acetylcholinesterase (hAChE) is the target of organophosphate nerve agents. Hence, there is an active interest in studying the mechanism of inhibition and recovery of enzymatic activity, which could lead to better countermeasures against nerve agents. As hAChE is found in different oligomeric

The partition‐of‐unity method based on FE‐Meshfree QUAD4 element synthesizes the respective advantages of meshfree and finite element methods by exploiting composite shape functions to obtain high‐order global approximations. This method yields high accuracy and convergence rate without necessitating extra nodes or DOFs.

A global survey of intramolecular isopeptide bonds
Abstract Many proteins harbor covalent intramolecular bonds that enhance their stability and resistance to thermal, mechanical, and proteolytic insults. Intramolecular isopeptide bonds represent one such covalent interaction, yet their distribution across protein domains and organisms has been largely unexplored.
