A Dynamic Gate Enables Regioselective Hydroxylation of Free Arginine by a Non‐Canonical Heme Enzyme

open access: yesAdvanced Science, EarlyView.
The YqcI/YcgG enzyme AglA employs a unique “sandwich” fold and a dynamic gating mechanism to selectively hydroxylate AMPn‐Arg at Nε. Site‐directed mutations reprogram regioselectivity or enable activity on free arginine by altering hydrogen‐bond networks, precisely positioning substrates.

A Parametric Bootstrap Test for Cycles [PDF]

open access: yes
The paper proposes a simple test for the hypothesis of strong cycles and as a by-product a test for weak dependence for linear processes. We show that the limit distribution of the test is the maximum of a (semi)Gaussian process G(t), t ? [0; 1]. Because

Proteogenomic Characterization Reveals Subtype‐Specific Therapeutic Potential for HER2‐Low Breast Cancer

open access: yesAdvanced Science, EarlyView.
Multiomic profiling of HER2‐low breast cancer identifies three proteomic subtypes with distinct therapeutic strategies: endocrine, antiangiogenic, and anti‐HER2 therapies. Genomic and lactate modification landscapes are detailed, providing insights for precise management.

Functional, Pharmacogenomic, and Immune Landscapes of Long Non‐Coding RNAs in Cancer

open access: yesAdvanced Science, EarlyView.
A systematic analysis of 33 cancer types reveals widespread associations between lncRNAs and cancer pathways, drug responses, immune features, and immunotherapy outcomes. The study identifies key lncRNAs linked to therapeutic response and adverse events and introduces PILNC, an interactive web portal for exploring the functional, pharmacogenomic, and ...

Hump‐Shaped Relationship Between Microbial Carbon Use‐Efficiency and Soil Organic Carbon in Alpine Grasslands

open access: yesAdvanced Science, EarlyView.
On the Qinghai–Tibetan Plateau, microbial carbon use efficiency (CUE) peaks at intermediate soil organic carbon levels and declines thereafter. In carbon‐rich soils, the formation of stable mineral‐associated organic carbon is decoupled from microbial CUE.

Evolutionary Divergence of an Ethylene‐Responsive Transcriptional Cascade Governs a Dose‐Dependent Balance between Cotton Fiber Length and Strength

open access: yesAdvanced Science, EarlyView.
A tunable, ethylene‐responsive cascade governing the dose‐dependent balance between fiber length and strength is unveiled. Elevated ethylene strengthens modern tetraploid cotton (G. hirsutum) fibers but elongates those of its diploid ancestor (G. arboreum). This phenotypic switch is traced to an evolutionary functional inversion of a conserved EIN3‐ERF‐
