Abstract

Intricate coupling between metabolism and protein post-translational modifications (PTMs) has emerged as a fundamental aspect of cellular regulation. Recent studies demonstrate that protein modifications can originate from diverse metabolites, and that their regulation is closely tied to the cellular metabolic state. Here we explore recently uncovered PTMs, including the concept of 'modification of a modification', as well as associated feedback and feedforward regulatory mechanisms, in which modified proteins impact not only related metabolic pathways but also other signaling cascades affecting physiology and diseases. The recently uncovered role of nucleus-localized metabolic enzymes for histone modifications additionally highlights the importance of cell-compartment-specific metabolic states. We further comment on the utility of untargeted metabolomics and proteomics for previously unrecognized PTMs and associated metabolic patterns. Together, these advances have uncovered a dynamic interplay between metabolism and PTMs, offering new perspectives for understanding metabolic regulation and developing targeted therapeutic strategies.
