Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Research on Legal Status of Commissionnaire under Agency Permanent Establishment Rules [PDF]
代理型常设机构规则是税收协定中协调来源国税收管辖权和居民国税收管辖权的重要规则之一,它关注的是外国企业通过代理人在一国进行的活动是否构成外国企业经营活动的延伸。近年来,跨国贸易中出现的佣金经销商模式,对现行代理型常设机构规则构成了极大挑战。本文将从代理型常设机构规则出发,结合实践中的佣金经销商案例,对佣金经销商是否构成现行规则下的代理型常设机构进行分析,以揭示现行规则的不足,进而对代理型常设机构的最新发展进行评析,为我国应对跨国贸易中的佣金经销商提出建议。 本文包括引言、正文和结语三个部分 ...

Diversity and complexity in neural organoids
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

The new permanent establishment
The PE is a century-old concept with a fundamental role in the international taxation system via the fair allocation of taxing rights over cross-border business profits within the source-residence principles equilibrium, as a vital threshold for source taxation. Throughout its existence, this pivotal element has relied on its founding principles, which

AAA+ protein unfoldases—the Moirai of the proteome
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
