L7 Bacterial sensing and response Flashcards
1
Q
What is Helix turn helix? (simple)
A
A DNA binding motif (reoccuring pattern or structural element.)
2
Q
_____ turn _____ is found in many ________ involved in gene __________
A
Helix. helix
proteins
Regulation
3
Q
Where is Helix turn helix found?
A
In a variety of proteins involved in gene regulation.
4
Q
What does Helix turn Helix have to do with bacteria?
A
Bacteria need to respond and adapt to environmental changes. the HTH motif allows them to do that by controlling the expression of specific genes.
5
Q
What is a transcription factor?
A
A protein that regulates the expression of genes by controlling the process of transcription.
6
Q
What is a motif?
A
small regions of protein three-dimensional structure or amino acid sequence shared among different proteins
7
Q
What is a dimer?
A
