The phrase "activity which competes" is correct and usable in written English.
It can be used to describe an action or event that is in competition with another.
Example: "The new marketing campaign is an activity which competes with our existing strategies for customer attention."
Alternatives: "competing activity" or "rival activity".
DNA methylation and demethylation result from the regulation of different enzymatic activities, which compete with each other for DNA access.
However, more recently, it has also been proposed that conformational changes in a "gating loop" (residues 398 413) result in voltage-triggered activity due to the movement of E411, which competes with the substrate for the active site.
Adenylyl-sulfate kinase activity, forming 3'-phospho-5'-adenosinephosphosulfate, which competes with adenylyl-sulfate reductase for its substrate, was represented in the EST dataset.
Precocious translation of recombinant TBP mRNA allows pre-MBT promoter activity in frog embryos, but only in combination with competitor DNA, which competes for chromatin assembly [ 49, 52].
The hepatic activity of GCK is inhibited by its regulatory protein GCKR in a dose-dependent manner, which competes with glucose for binding site [19].
With respect to PERK, inhibition is possible with the synthetic compound GSK2656157 (Table 1), which competes with ATP to bind PERK specifically, and thus inhibits its kinase activity [ 164].
The induced AhRR forms a heterodimer with ARNT, which competes with AhR/ARNT heterodimer to bind to the XRE sequence, consequently inhibiting AhR transcriptional activity.
33 This is a truncated form of the CDX2 protein (miniCDX2) which competes for the DNA binding with its wild-type counterpart but lacks the transactivation activity.
In addition, the NF- κB inhibitor peptide, SN50, which competes for the nuclear translocation sequences of NF- κB, attenuated both the increased DNA binding of NF- κB induced by PIF and the increased proteasome chymotrypsin-like enzyme activity.
The suppression of hTERT promoter activity could be reversed by c-Myc, which competed with NR2F2 for binding to the E-box.
Traditional continuous fMRI acquisition methods produce sounds >90 dB which compete with stimuli or produce neural activation masking evoked activity.
