Water chemistry and algal phosphatase activity in zinc-contaminated streams [PDF]

open access: yes, 1990
A study was carried out on algal phosphatase activity and water chemistry in zinc-contaminated streams in the Northern Pennine Orefield. Fourteen field sites were studied; They ranged from low contaminated to high-zinc sites (0.1 mg 1(^-1) to 19.4 mg 1(^-

Acid phosphatase assay.

open access: yes, 2013
Acid phosphatase activity was determined from whole cell lysates of F. tularensis acid phosphatase mutants by a fluorometric method using DiF-MUP as the substrate. The data are presented as percent of wild type phosphatase activity.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Distribution of Phosphate Solubilizing Bacteria and Soil Phosphatase Activity in Different Land Uses

open access: yesمجله آب و خاک, 2016
Introduction: Phosphorous is one of the essential macronutrients for plant growth and development but its mobility in soil is very low. The utilization of the soil biological potential, in particular phosphate solubilizing bacteria, is an efficient way ...

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Modifications induced by ascorbic acid on alkaline phosphatase fluorescence

open access: yes, 1984
Ascorbic acid, isoascorbic acid and dehydroascorbic acid quench the tryptophyl fluorescence of alkaline phosphatase. The quenching is protein aspecific, although its extent reflects the different inhibitory efficiency of the compounds.

ACID PHOSPHATASE ACTIVITY IN MELANOSOMES OF MELANOCYTES [PDF]

open access: yes, 1968
A combined cytochemical and electron microscopic demonstration of acid phosphatase activity of melanosomes in melanocytes was carried out on B-16 and Harding-Passey mouse melanoma and the retinal pigment epithelium of white leghorn chick embryos.
