Study Notes
Autocatalytic Cycle
- Represents a typical mechanism for self-replication reactions where products catalyze their own formation.
- Highlights emergent properties associated with peptide self-replication, showcasing complex interactions.
Bistable Behavior
- Observed in thiodepsipeptides operating far from thermodynamic equilibrium.
- Indicates that such systems can exhibit two stable states, impacting their self-replicating capabilities.
Spontaneous Diversification
- Self-assembly is driven by self-replication processes, leading to diverse structural outcomes.
- Oxidation of a mixture containing two distinct dithiol building blocks with different peptide sequences results in the generation of a variety of disulfide macrocycles.
Emergence of Hexameric Rings
- The initial formation of hexameric rings from disulfide macrocycles reflects self-replicating characteristics.
- The first set of hexameric rings, referred to as mutants, triggers the subsequent cross-catalytic formation of a second set with varying building block compositions.
- Suggests a potential ancestral relationship between the different sets of hexamer mutants, emphasizing evolutionary connections in peptide self-replication.
