Protein phosphorylation in yeast mitochondria [PDF]

open access: yes, 1987
We describe the identification and submitochondrial localization of four protein kinases and of their target proteins in derepressed yeast mitochondria. The activity of one of the kinases depends on the presence of cyclic AMP (cAMP).

DMS‐MaPseq and DREEM Analyses Implicate the Critical Role of RNA Structural Dynamics in Turnip Yellow Mosaic Virus Pathogenicity

open access: yesAdvanced Science, EarlyView.
RNA structural profiling of Turnip Yellow Mosaic Virus by DMS‐MaPseq and DREEM analyses uncover that viral genome‐wide RSS is highly complicated and heterogeneous, with alternative RSSs widely distributed across the genome. Notably, the viral 3’ tRNA‐like structure adopts alternative conformations in vivo.

Mapping and Functional Role of Phosphorylation Sites in the Thyroid Transcription Factor-1 (TTF-1) [PDF]

open access: yes, 1996
The phosphorylation of thyroid transcription factor-1 (TTF-1), a homeodomain-containing transcription factor that is required for thyroid-specific expression of the thyroglobulin and thyroperoxidase gene promoters, has been studied.

Alkyltransferase Ribozyme for Site‐Specific N4‐Cytidine Alkylation

open access: yesAngewandte Chemie, Volume 138, Issue 20, 11 May 2026.
CSAR is the first ribozyme that catalyzes direct alkylation of an exocyclic amino group of an RNA nucleobase. The ribozyme was isolated as a self‐labeling catalyst from an in vitro selection library and engineered into a trans‐active ribozyme that catalyzes the transfer of a benzyl group from an O6‐modifed guanine to the N4 amino group of a specific ...

Effect of vitamin K depletion and restoration on sphingolipid metabolism in Bacteroides melaninogenicus

open access: yesJournal of Lipid Research, 1972
Bacteroides melaninogenicus requires vitamin K for normal growth. Cells incubated in a vitamin K-free medium form defective cell envelopes. Studies with vitamin K-grown “K(+)” and vitamin K-depleted “K(–)” cells showed that [14C]choline and [14C]glycerol

5'-terminal structure of poliovirus polyribosomal RNA is pUp [PDF]

open access: yes, 1976
Poliovirus RNA purified from virus-specific polyribosomes does not contain m7G in a 5'-5'-pyrophosphate linkage at its 5'-end. The only potential 5'-end found in ribonuclease digests of this RNA is pUp, which is present in a yield of 1 mole/mole of ...

Ribozyme für die RNA‐katalysierte Methylierung und Markierung von RNA

open access: yesAngewandte Chemie, EarlyView.
Ribozyme sind vielseitige Werkzeuge für die präzise Modifikation von RNA. Das Reaktionsspektrum in‐vitro‐selektierter Ribozyme reicht vom Einbau funktioneller Gruppen und Fluorophoren bis zu natürlichen RNA‐Methylierungen. Dieser Übersichtsartikel präsentiert Cofaktor‐abhängige Ribozyme für die positionsgenaue Markierung und Modifikation von RNA ...

Protein kinase-mediated phosphorylation of a purified sterol ester hydrolase from bovine adrenal cortex.

open access: yesJournal of Lipid Research, 1978
Sterol ester hydrolase (cholesterol esterase, E.C. 3.1.1.13) of bovine adrenal cortex has been extensively purified by ammonium sulfate fractionation, acid precipitation, hydroxylapatite chromatography, and Sephadex G-200 chromatography.

Phosphorylation of Spinophilin Modulates Its Interaction with Actin Filaments [PDF]

open access: yes, 2003
Spinophilin is a protein phosphatase 1 (PP1)- and actin-binding protein that modulates excitatory synaptic transmission and dendritic spine morphology. We report that spinophilin is phosphorylated in vitro by protein kinase A (PKA).
