Phosphorylation of chloroplast ribulose bisphosphate carboxylase/oxygenase small subunit by an envelope-bound protein kinase in situ [PDF]

open access: yes, 1983
A new protein kinase of the cAMP independent type was found to be bound to the outer envelope membrane of spinach chloroplasts. While stimulated by Mg2+ and inhibited by ADP, the enzyme showed no response to conventional protein substrates and was ...

Human FASTK preferentially binds single‐stranded and G‐rich RNA

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 729-748, February 2026.
Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Determination of Lactic Acid Bacteria Viability in the Small Intestine of Catfish (Pangasius djambal) by Using the 32P Radioisotope

open access: yesAtom Indonesia, 2015
The viability of probiotics is important to be determined, as is its probiotic potency in the small instestine of fish. The result can be used as a basis to determine the feeding frequency of the probiotics to the fish.The aim of this study is to gain ...

The Uptake of 32P by Brown Planthoppers (Nilaparvata Lugens Stal) Gonads

open access: yesJournal of Mathematical and Fundamental Sciences, 2019
. The radioisotop 32P has been used quite extensively in the field of insect ecology and insect physiology. It has been widely known that 32P is one of the several isotopes applied to tag the insects for migration studies, to estimate the sap uptake or ...

Cinética do fósforo em tecidos de ovinos em crescimento alimentados com diferentes fontes de cálcio Kinetics of phosphorus in tissues of lambs fed different sources of calcium

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2007
Foram utilizados 12 cordeiros machos, inteiros, com peso médio de 31,6kg. Os cordeiros foram alimentados com dietas à base de milho e farelo de soja, suplementadas com diferentes fontes de cálcio: calcário calcítico (CC), feno de alfafa (FA), polpa ...

A tale of two inositol trisphosphates. [PDF]

open access: yes, 2016
Between spring 1982 and autumn 1984 the physiological role of Ins(1,4,5)P3 as a calcium-mobilizing second messenger was first suggested and then experimentally established.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

open access: yesMolecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Phospholipid Interconversion and Transport Are Altered in Glaucoma

open access: yesThe FASEB Journal, Volume 40, Issue 2, 31 January 2026.
Decreased phosphatidylserine (PS) and increased phosphatidylethanolamine (PE) occur in both trabecular meshwork (TM) cells and aqueous humor due to aberrant phosphatidylserine decarboxylase (PSD) over‐expression, and variation in levels of individual PS or PE species differing by only a few acyl chains occurs due to impaired lipid transport due to ...

Translocation of 32P from leaves to seeds of sunflower and associated biochemical changes in young and mature leaves during seed-filling

open access: yesActa Societatis Botanicorum Poloniae, 2014
Transport of 32P from mature leaves was studied at stage I (ray florets opening), stage II (50% florets opening) and stage III (central disc florets opening) of the capitulum in order to ascertain the capacity of developing seeds to draw metabolites ...
