The phrase "activate one or more" is correct and usable in written English.
It can be used in contexts where you are instructing someone to enable or turn on one or several items or features.
Example: "To proceed with the setup, please activate one or more of the available options in the menu."
Alternatives: "enable one or more" or "turn on one or more".
Epidermal growth factor (EGF) is one of more than 10 ligands able to activate one or more of the four receptors belonging to the EGF system.
Recent structural data on GPCRs using a variety of spectroscopic approaches suggest that GPCRs adopt a dynamic conformational landscape, with ligands stabilizing subsets of these states to activate one or more downstream signaling effectors.
Single-step load restoration in a substation usually aims to activate one or more circuits at the same time.
In the intrinsic pathway (route 2), diverse stimuli that provoke cell stress or damage typically activate one or more members of the BH3-only protein family.
This is more applicable to motes that use multiple sensors, which is currently not the case in our prototype (although it could be easily extended with other sensors; for instance, one could simply activate one or more of the onboard sensors of the TelosB).
We hypothesized that MAPK signaling may be required to activate one or more of these transcriptional regulators by phosphorylation.
Activating one or more among the BH3-only proteins culminates in allosteric activation of the pore-forming proteins Bax and Bcl-2 antagonist/killer (Bak).
In response to intracellular stress events ranging from starvation to pathogen invasion, the cell activates one or more forms of macroautophagy.
These modifications could affect transcriptional programs by activating one or more transcription factors able to control calcium homeostatic genes.
Typically, a stimulated GPCR activates one or more types of G proteins (the transducers) which further activate specific effectors of various downstream pathways.
Because βTrCP is known to recognize phosphorylated substrates, it is likely that TLR signaling activates one or more kinases that phosphorylate Perforin-2 prior to its association with the CRL.
