One of the main goals of proteomics is to unravel the many modifications important for biological activity. Post-translational modifications (PTMs) extend the range of protein function by attaching it ...

Protein AMPylation represents a specialised post‐translational modification (PTM) in which an adenosine monophosphate (AMP) moiety is covalently attached to specific amino acid residues on target ...

Chief among these is accurately and reproducibly mimicking natural post-translational modifications. Identifying and characterizing such modifications impact half-life, quality, cost, and potential ...

Tsukuba, Japan—Proteins are subject to post-translational chemical modifications that result in functional diversity. Methylation is one such modification that is generally believed to occur on lysine ...

The amino acid side chains of proteins undergo various post-translational modifications (PTMs) which significantly impact protein function and mediate complex cellular events. Measuring the dynamics, ...

Biochemists from the National University of Singapore (NUS) have discovered a new subclass of trifunctional enzymes in gram-positive bacteria, which play a critical role in the biosynthesis of an ...

When it comes to enzymes, protein abundance does not necessarily translate into protein activity: Post-translational modifications such as phosphorylation can dramatically alter enzyme function.

Citrullination, a transformative protein post-translational modification, is gaining recognition for its wide-ranging impact on cellular function and human disease. This process, driven by the enzyme ...

Lactylation, a recently identified post-translational modification, has emerged as important for immune regulation, tissue repair, cancer cell metabolism, and now, potentially, Alzheimer’s disease. In ...

An Iowa State University research team has discovered a method for modifying the function of an enzyme crucial to fat production, which could lead to more effective treatments for childhood obesity ...
