Causal analysis of A domain substrate specificity.

open access: yes, 2023
The specificity-conferring code distance used is alignment-score distance. A domain sequence distance used is p-distance. The loop length distance used is Euclidean distance. r is Pearson correlation coefficient. A.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The Substrate and Anomeric Specificity of Fructokinase

open access: yesJournal of Biological Chemistry, 1973
Abstract Fructokinase from beef liver is shown to be specific for the β-furanose anomer of d-fructose (and the α anomer of l-sorbose) by showing that certain 2,5-anhydroalditols are substrates, while other 2,5-anhydro compounds, 2,6-anhydro-d-mannitol, and 2,6-anhydro-d-glucitol are not.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Substrate Specificity of Soybean Lipoxidase

open access: yesJournal of Biological Chemistry, 1969
Abstract Purified soybean lipoxidase was used to test the substrate specificity of all cis,cis-methylene-interrupted isomers of linoleic acid. The natural 9,12-isomer was found to be the best substrate, and the 13,16-isomer 50% as effective. The presence of calcium ions broadened the pattern of specificity.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Current understanding of substrate specificity and regioselectivity of LPMOs

open access: yesBioresources and Bioprocessing, 2020
Renewable biomass such as cellulose and chitin are the most abundant sustainable sources of energy and materials. However, due to the low degradation efficiency of these recalcitrant substrates by conventional hydrolases, these biomass resources cannot ...

Screening of DUB activity and specificity by MALDI-TOF mass spectrometry [PDF]

open access: yes, 2014
Deubiquitylases (DUBs) are key regulators of the ubiquitin system which cleave ubiquitin moieties from proteins and polyubiquitin chains. Several DUBs have been implicated in various diseases and are attractive drug targets. We have developed a sensitive

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Substrate Specificity of a Cationic Peptidase from L

open access: yesNatural Product Communications, 2008
A cationic peptidase, named hemisphaericin-C, has been purified from the juice of Bromelia hemisphaerica fruits by ammonium sulfate precipitation, gel filtration on Sephadex G-75 and cationic exchange chromatography on carboxymethyl cellulose (CMC), to ...
