Characterization and relative quantification of phospholipids based on methylation and stable isotopic labeling[S]

Journal of Lipid Research, 2016
Phospholipids (PLs), one of the lipid categories, are not only the primary building blocks of cellular membranes, but also can be split to produce products that function as second messengers in signal transduction and play a pivotal role in numerous ...

Multi-state recognition pathway of the intrinsically disordered protein kinase inhibitor by protein kinase A

eLife, 2020
In the nucleus, the spatiotemporal regulation of the catalytic subunit of cAMP-dependent protein kinase A (PKA-C) is orchestrated by an intrinsically disordered protein kinase inhibitor, PKI, which recruits the CRM1/RanGTP nuclear exporting complex.

Fructose metabolism in Chromohalobacter salexigens: interplay between the Embden–Meyerhof–Parnas and Entner–Doudoroff pathways [PDF]

, 2019
Background The halophilic bacterium Chromohalobacter salexigens metabolizes glucose exclusively through the Entner–Doudoroff (ED) pathway, an adaptation which results in inefficient growth, with significant carbon overflow, especially at low salinity ...

Discovery and analysis of a new class of triterpenes derived from hexaprenyl pyrophosphate

Engineering Microbiology, 2022
Triterpenes are derived from squalene or oxidosqualene. However, a new class of triterpenes derived from hexaprenyl pyrophosphate has been recently discovered, formed by a new family of chimeric class I triterpene synthases. The cyclization mechanisms of
