Succinate and its carrier Sfc1 mediate metabolic control of mitochondrial protein import by the TIM23 translocase

Koyeli Das, Rituparna Samanta, Tamar Ziv…·Ophry Pines

The paper shows that succinate and its carrier Sfc1 regulate mitochondrial protein import via interaction with Tim23, affecting enzyme localization between mitochondria and cytosol.

Functional Proteomics of ABC Importers Reveal Synchronization of Mechanisms, Cellular Abundances, and Counterintuitive Stoichiometries

Hiba Qasem Abdullah, Nurit Livnat Levanon, Michal Perach…·Oded Lewinson

The paper develops a proteomic approach to study E. coli ABC importers, revealing abundance variations, inverse correlations between substrate-binding protein affinities and permease interactions, and counterintuitive stoichiometries.
