Words similar to holoenzyme
Example sentences for: holoenzyme
How can you use “holoenzyme” in a sentence? Here are some example sentences to help you improve your vocabulary:
The bacterial-specific SBHM domains present in the β and β' subunits are typically located on the periphery of the holoenzyme, which makes them accessible for interactions with other proteins.
The recruitment model for transcriptional activation stipulates that eukaryotic transcription is driven mainly by recruitment of preformed RNA polymerase holoenzyme to specific sites on the DNA [ 3 ] . According to this model, peptides may bind one of numerous proteins that guide holoenzyme to the lexA binding site.
The 1.0 MDa complex contains yCCR4, yPOP2 (also referred to as yCAF1) and at least five yNOT1-5 proteins [ 5 6 7 ] . In this complex, yPOP2 independently binds to yCCR4 and yNOT1, and is absolutely required for yCCR4 to associate with the 1.0 MDa complex [ 6 7 ] . In the 1.9 MDa complex, yCCR4 binds to proteins such as yDBF2, a cell-cycle regulated protein kinase [ 2 ] , yCAF4 and yCAF16, and is essential for the interaction of both yCAF4 and yCAF16 with ySRB9, a component of the RNA polII holoenzyme [ 8 ] . yCCR4 was also reported to be associated with Paf1, Cdc73, and Hpr1 in a RNA polII complex distinct from the SRBP-containing holoenzyme [ 9 ] . Accordingly, yCCR4 contains, in its central region, a leucine-rich repeat (LRR) domain [ 10 ] which was demonstrated to be necessary for yCCR4 binding to the yPOP2 [ 5 11 ] , yDBF2 [ 2 ] , yCAF4 and yCAF16 [ 8 ] components of the CCR4-NOT complex.
In addition, BRCA1 can act as a transcriptional transactivator in yeast reporter assays [ 26, 27] and binds the RNA polymerase II holoenzyme, a component of the basal transcription machinery [ 25].
Alternatively, these basic peptides may bind different regions of the holoenzyme component(s) recognized by acidic peptides, or entirely different subunits [ 21 ] .
