The strongest type of noncovalent chemical bond in an aqueous environment.
What is an ionic bond?
Bonding of two or more polypeptide chains.
What is quaternary level?
This enzyme constant describes how many substrate molecules one enzyme converts to product per second when fully saturated.
What is Kcat?
The fundamental structural unit of chromatin, consisting of a segment of DNA wound around a core of eight histone proteins.
What is a nucleosome?
Evolved when an ancient archaeal anaerobe engulfed an aerobic bacterial cell
What is Mitochondria?
This spiral-shaped protein structure is stabilized by hydrogen bonds along the peptide backbone.
What is a Alpha Helix?
A ligand that binds to a site other than the active site to regulate enzyme activity without competing with substrate.
What is an allosteric ligand?
Connects one sugar to the next
What is phophodiester bonds?
This weak intermolecular attraction forms when a hydrogen atom bonded to oxygen, nitrogen, or fluorine is drawn to a nearby electronegative atom, helping stabilize water, DNA, and proteins.
What are hydrogen bonds?
The self-assembled protein shell that protects a virus's genome.
What is a viral capsid?
This cellular system tags proteins with a small regulatory protein to target them for degradation or alter their activity
What is the ubiquitin-conjugating system?
This organized DNA protein complex packages genetic material into nucleosomes and fibers, controlling gene accessibility.
What are Chromatin Structures?
