This implies that the euchromatic pattern is the default pattern ... histones to CAF-I at the replication fork. Resetting epigenetic patterns on chromatin entails more than histone acetylation.

... [83,84]. Taking into account that oxylipins effectively induce TGA tran- scription factor expression, it is attractive to speculate that, as yet undetected, NPR1-like transcriptional regu- lators ... Nevertheless, it may be suggested that the addition of RES to GSH renders them inactive or modulates their biological impact. In addition to GST induction, the transcription of lipid transfer pro...

... the substrate within the catalytic pocket of the thioesterase might be influenced. To further investigate the biocombinatorial potential of TioS T- TE, a set of d-Ser1 substituted tetrapept- idyl-SNACs ... tetrapept- idyl-SNACs (TL7-TL10) was tested. By contrast to TL1, the Ser-substituted TL7 was cyclized leading to the conclusion that only l-Cys3 influences macrothiol- actonization. In this...
