DOI: http://dx.doi.org/10.7554/eLife.00005.002 The combined antagonistic activities of the Polycomb group (PcG) and the Trithorax group (TrxG) protein complexes contribute to correct homeotic gene expression and accurate cell fate maintenance.
The catalyst combines two antagonistic active functions on one solid catalyst, allowing acid base tandem conversions in a single pot.
Enzymes can efficiently catalyze multistep processes that give various types of biomolecules. 1 Remarkably, many enzymes combine two antagonistic catalytic functions, such as acid and base functions.
As a result of combined but antagonistic actions of Isw1 and Isw2, a nucleosome free region is created on the gene body along with strong positioning of the US nucleosome.
Building on recent studies that determined a reciprocal relationship between DNA methylation and Polycomb activity, we demonstrate that, in methylation-deficient embryonic stem cells (ESCs), CpG density combined with antagonistic effects of H3K9me3 and H3K36me3 redirects PcG complexes to pericentric heterochromatin and gene-rich domains.
(Scott) 'YOURS, MINE AND OURS' (PG, 90 minutes) Dennis Quaid and Rene Russo inhabit roles originated by Henry Fonda and Lucille Ball in this snug, airtight remake of the 1968 comedy about the combining of two antagonistic families with 18 children between them.

It may seem difficult to combine the aforementioned antagonistic behaviors from a neurobiological standpoint.
As with 2,3-D, our results indicate that the identified benzaldehydes with thymol increased antifungal activity of each compound when combined, with no antagonistic or neutral interactions.
This paper illustrates a methodological procedure for single electron transfer (SET) antioxidant assays to determine the synergistic and antagonistic effects of combining binary mixtures of antioxidants.
