Example: "The activity is not only enjoyable but also educational, providing participants with valuable skills."
Alternatives: "activity is not just" or "activity is more than".
Together, this exemplifies how histone demethylase activity is not only defined by the active site itself, but also requires complex interactions between the substrate and addition domains.
OR-α signalling activity is not only induced by oestrogen, but OR-α is also activated as a transcriptional transactivator in a hormone-independent manner by phosphorylation of serines 104/106 by cyclin A-cdk2 (Rogatsky et al, 1999) and by direct binding of OR-α to cyclin D1 (Zwijsen et al, 1997).
Another issue is that RIPK1 kinase activity is not only confined to necroptosis but is also involved in ERK activation and in apoptosis when IAP is depleted.
Human activity is not only draining the river and its aquifers of water, it is spitting gobs of poison into the flow that remains.
This type of activity is not only safe, but fun and beneficial – as after eight weeks speaking only French/German/Spanish, you're almost guaranteed an A in speaking tests and you'll probably go up a grade or two overall".
Scientists familiar with the work, to be published Friday in the journal Science, said it provided fresh evidence that human activity is not only warming the globe, particularly the Arctic, but could also even fend off what had been presumed to be an inevitable descent into a new ice age over the next few dozen millenniums.
■ For elderly people, a group long considered sexually demure if not altogether chaste, vigorous sexual activity was not only possible but normal.

Locomotor activity was not only increased during the procedure, but also did not exceed the peak levels found during undisturbed wakefulness.
This reduction in activity was not only rescued when the YJU3 gene was reintroduced, but PEA hydrolysis was actually greatly increased (Figure 5A).
Finally, by using heterologous expression of LLO and purified LLO encapsulated in liposomes, we showed that LLO activity was not only necessary but sufficient to trigger autophagy.
