Structural insights into manganese-dependent arylsulfatase from Enterococcus faecium and its catalytic promiscuity [PDF]

open access: yesmBio
Catalytic promiscuity, wherein enzymes catalyze multiple distinct reactions by stabilizing various transition states, is well documented in the alkaline phosphatase superfamily.

Exploring the Venom Gland Transcriptome of Bothrops asper and Bothrops jararaca: De Novo Assembly and Analysis of Novel Toxic Proteins [PDF]

open access: yesToxins
Previous proteomic studies of viperid venom revealed that it is mainly composed of metalloproteinases (SVMPs), serine proteinases (SVSPs), phospholipase A2 (PLA2), and C-type lectins (CTLs).

Soil enzymatic activity under coffee cultivation with different water regimes associated to liming and intercropped brachiaria

open access: yesCiência Rural, 2021
: This research evaluated the effects of coffee cultivation with two different water regimes associated or not with liming and the presence/absence of brachiaria as intercrop on the activities of the soil enzymes β-glucosidase, arylsulfatase and acid ...

Soil enzymatic activity and wheat grain yield under cover crop systems

open access: yesPesquisa Agropecuária Tropical, 2023
For years, the impacts of using cover crops in productive systems have been measured by their relation with soil chemical and physical characteristics. Consequently, the effects on the soil microbiological characteristics have been little explored.

Pseudo arylsulfatase A deficiency Biosynthesis of an abnormal arylsulfatase A [PDF]

open access: yesFEBS Letters, 1987
Pseudo arylsulfatase A deficiency, an asymptomatic condition, and metachromatic leukodystrophy, a severe neurodegenerative disease, are both associated with profound reductions of arylsulfatase A activity in man. We now report that with metabolic labelling, cultured pseudo deficient cells synthesized about 20% of the normal amount of arylsulfatase A at

Soil microbiological properties and enzyme activity in agroforestry systems compared with monoculture, natural regeneration, and native Caatinga

open access: yesBioscience Journal, 2020
The objective of this study was to evaluate the influence of agroforestry systems of different ages (AFS1: one-year old; AFS5: five-years old) on the biological attributes of soil; the following systems were used for comparison: a slash-and-burn (SBF ...

Arylsulfatase A pseudodeficiency incidence in Turkey

open access: yesThe Turkish Journal of Pediatrics, 2000
Pseudodeficiency (Pd) in arylsulfatase A (ASA) is a relatively frequent condition in healthy individuals. It produces a reduction in enzyme activity similar to that found in metachromatic leukodystrophy (MLD). A variable incidence of the Pd allele

Microbial Biomass and Enzyme Activity of Soil Under Clonal Rubber Tree Plantations

open access: yesFloresta e Ambiente, 2020
Our study aimed to evaluate the influence of rubber tree plantations (Clones IAN 873 and FX 3864) on microbial activity, total organic carbon (TOC), and soils chemical attributes, using as reference pasture and secondary forest, in Rio de Janeiro.

Changes in Soil Sulphur Fractions as Influenced by Nutrient Management Practices in Mulberry

open access: yesLand, 2023
Sulphur (S) plays a vital role in improving the quality of mulberry leaves because of its involvement in protein synthesis. The knowledge of different pools of S in soils and its bioavailability for mulberry nutrition is thus, required for optimizing S ...
