Key Mechanisms and Functional Diversity
When analyzing the post-translationally modified peptides mechanism of action, one must consider how the precursor is matured. The maturation process often involves the cleavage of a leader peptide, leaving behind a core peptide that has been significantly altered.
These small post-translationally modified peptides are not merely structural oddities; they are important regulators of plant growth and development. In various biological systems, these molecules act as signaling agents. The post-translationally modified peptides function is highly dependent on the specific PTMs applied, such as phosphorylation, glycosylation, or the creation of thioether bonds.
