posttranslational
Tính từ
This term is a specialized technical adjective used almost exclusively within biochemistry and molecular biology. It describes the critical window of time after a ribosome has finished synthesizing a polypeptide chain but before that protein becomes biologically active or reaches its final destination.
Usage is typically restricted to scientific literature, textbooks, and laboratory reports. It is frequently paired with nouns like modifications, processing, or folding to describe the chemical changes—such as phosphorylation or glycosylation—that determine a protein's ultimate function and structure.
