Acylation is a post-translational modification involving the attachment of acyl groups, such as acyl-CoA, to proteins. This modification plays a pivotal role in regulating key biological processes including epigenetics, energy metabolism, protein trafficking, and molecular interactions. Acylation research is a dynamic field in life sciences, with studies expanding beyond acetylation to include propionylation, malonylation, glutarylation, succinylation, and crotonylation.
