Graspetides
A class of ribosomally synthesized and post-translationally modified peptides (RiPPs).
Scientific: BiopharmaceuticalsBiotechnology / Peptides
Graspetides are a special type of peptide made by living organisms. They have unique ring structures that make them strong and give them different abilities, like fighting bacteria or viruses. Scientists are studying how these rings form to learn more about how graspetides work.
Ribosomally synthesized
Produced by ribosomes, the cellular machinery responsible for protein synthesis.
Scientific: BiopharmaceuticalsBiotechnology / Protein Synthesis
Ribosomally synthesized means that something was made using ribosomes. Ribosomes are tiny factories inside cells that build proteins from instructions in our DNA.
Post-translationally modified
Altered after protein synthesis.
Scientific: BiopharmaceuticalsBiotechnology / Protein Modification
Post-translationally modified means that something happens to a protein *after* it's been made. This can change how the protein works or what it does in the body.
RiPPs
Ribosomally synthesized and post-translationally modified peptides.
Acronym: BiopharmaceuticalsBiotechnology / Peptides
RiPPs are short chains of amino acids made by ribosomes. They're often changed after they're made to have special abilities.
Macrolactam
A cyclic amide formed by reaction between a carboxylic acid and an amine group within the same molecule.
Scientific: BiopharmaceuticalsBiochemistry / Peptide Structure
Macrolactam is a type of ring structure found in some peptides. It's made when a part of the peptide chain links back to itself, forming a circle.
Macrolactone
A cyclic ester formed by reaction between a carboxylic acid and an alcohol group within the same molecule.
Scientific: BiopharmaceuticalsBiochemistry / Peptide Structure
Macrolactone is another type of ring structure found in some peptides. It's made when a part of the peptide chain links back to itself, forming a circle.
ATP-grasp ligase
An enzyme family that catalyzes the formation of macrolactam or macrolactone linkages in peptides.
Scientific: BiopharmaceuticalsBiochemistry / Enzyme
ATP-grasp ligase is a type of enzyme that helps make macrolactam and macrolactone rings in peptides. It uses energy from ATP to do this.
Antimicrobial
Having the ability to kill or inhibit the growth of microorganisms.
Technical: PharmaceuticalsMedicine / Infectious Disease
Antimicrobial means something can fight off germs like bacteria and viruses.
Antiviral
Having the ability to kill or inhibit the growth of viruses.
Technical: PharmaceuticalsMedicine / Infectious Disease
Antiviral means something can fight off viruses.
Enzyme inhibitory
Preventing the activity of enzymes.
Technical: PharmaceuticalsMedicine / Biochemistry
Enzyme inhibitory means something can stop enzymes from working.
Molecular dynamics (MD) simulations
Computer simulations that model the movement and interactions of atoms and molecules over time.
Scientific: BiotechnologyBiochemistry / Computational Biology
Molecular dynamics (MD) simulations are computer programs that can show how atoms and molecules move and interact. They're used to understand how things work at a very small level.
Folding trajectories
The path that a molecule takes as it folds into its final three-dimensional structure.
Scientific: BiotechnologyBiochemistry / Protein Structure
Folding trajectories are the steps that a protein takes as it bends and twists to become its final shape.
Ring closure preference
The tendency of a molecule to form certain ring structures over others.
Scientific: BiotechnologyBiochemistry / Peptide Structure
Ring closure preference means that some proteins like to make certain types of rings more than others.
