Meanings of self-activating in английском

The copper complexes with the inherent redox active hydroquinone functionality cleave plasmid pBR322 DNA without exogenous agents by a self-activating mechanism.

The self-activating property also means that plant G proteins do not need and therefore do not have typical animal G protein-coupled receptors.

In contrast to animal G proteins, plant G proteins are self-activating, and therefore regulation of G activation in plants occurs at the deactivation step.
