Arylsulfatase Activity in Salt Marsh Soils [PDF]

Applied and Environmental Microbiology, 1979
The presence of arylsulfatase(s) was confirmed in salt marsh soils. The temperatures of maximum activity and inactivation, the pH range over which the enzyme was active, and the K m values were similar to those of soil enzymes.

ARSA Variants Associated With Cognitive Decline and Long‐Term Preservation of Motor Function in Metachromatic Leukodystrophy

Journal of Inherited Metabolic Disease, Volume 48, Issue 5, September 2025.
ABSTRACT Patients with metachromatic leukodystrophy (MLD) show variable motor and cognitive decline. The ARSA variants c.256C>T, p.(Arg86Trp), c.257G>A, p.(Arg86Gln) and c.542T>G, p.(Ile181Ser) are associated with predominantly cognitive decline. This multinational study analyzed MLD onset type, presenting signs/symptoms, cognitive function, gross ...

Soil organic matter and enzyme activity in tropical sandy soils under integrated and conventional land uses

Soil Science Society of America Journal, Volume 89, Issue 5, September/October 2025.
Abstract The preservation of soil fertility is essential for ecosystem sustainability, particularly in tropical regions where agricultural intensification often leads to rapid degradation. This study evaluated the impact of different land‐use systems on soil organic matter (SOM), enzymatic activities, and soybean productivity in tropical sandy soils ...

EST analysis of gene expression in early cleavage-stage sea urchin embryos [PDF]

, 1999
A set of 956 expressed sequence tags derived from 7-hour (mid-cleavage) sea urchin embryos was analyzed to assess biosynthetic functions and to illuminate the structure of the message population at this stage.

Identification and characterization of a glycosulfatase-encoding gene cluster in Bifidobacterium breve UCC2003 [PDF]

, 2016
Bifidobacteria constitute a specific group of commensal bacteria, typically found in the gastrointestinal tract (GIT) of humans and other mammals. Bifidobacterium breve strains are numerically prevalent among the gut microbiota of many healthy breast-fed

Diverse Cooccurring Metabolisms Support Sulfur and Methane Cycling in Wetland Surficial Sediments

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract The Prairie Pothole Region (PPR) of North America contains millions of small depressional wetlands with some of the highest methane (CH4) fluxes ever reported in terrestrial ecosystems. In saturated soils, two conventional paradigms are (a) methanogenesis is the final step in the redox ladder, occurring only after more thermodynamically ...

Long-Term Winter Cover Crops Alter the Soil Microbial Biomass and Enzyme Activities in Brazilian Oxisols

Agronomy
The diversification of cover crops grown in soils with granulometric variability may potentially enhance microbial community and enzyme activities. Thus, the main goal was to evaluate the effect of autumn/winter cover crop sequences and cash crops in ...

Individual heat map assessments demonstrate vestronidase alfa treatment response in a highly heterogeneous mucopolysaccharidosis VII study population. [PDF]

, 2019
Mucopolysaccharidosis (MPS) VII is an ultra-rare, progressively debilitating, life-threatening lysosomal disease caused by deficiency of the enzyme, β-glucuronidase. Vestronidase alfa is an approved enzyme replacement therapy for MPS VII. UX003-CL301 was

Activation Energy of Organic Matter Decomposition in Soil and Consequences of Global Warming

Global Change Biology, Volume 31, Issue 9, September 2025.
Activation energy (Ea) is the minimum energy necessary for (bio)chemical reactions defining reaction rates, e.g., organic matter transformations in soil. Based on the Ea database of enzyme activities, CO2 production, heat release during soil incubation, and thermal oxidation of soil organic matter, we assess the Ea of biotic and abiotic transformation ...
