Study Notes
Protein Structure
- The primary structure of a protein refers to the sequence of amino acids connected by peptide bonds.
- Peptide bonds are responsible for connecting amino acids in a protein's primary structure.
Protein Structure Prediction
- Online resources such as Phyre2 and I-TASSER can be used for protein structure prediction.
Protein Quaternary Structure
- The quaternary structure of a protein refers to the arrangement of multiple polypeptide chains (subunits) in a protein.
Protein Secondary Structure
- The secondary structure of a protein is characterized by the arrangement of alpha helices and beta sheets.
Protein Synthesis
- tRNA (transfer RNA) plays a crucial role in protein synthesis by carrying amino acids to the ribosome during translation.
Cellular Transport
- Exocytosis is the cellular process that involves the release of substances from a cell through vesicles.
Peroxisomes
- The main function of peroxisomes in a cell is to break down fatty acids and amino acids.
Post-Translational Modification
- Ubiquitination is a post-translational modification that involves the addition of ubiquitin to proteins, marking them for degradation.
Autophagy
- The main function of autophagy in a cell is to recycle damaged organelles and proteins.
Membrane Transporters
- The primary location for the classification of membrane transporters is the Transporter Classification Database (TCDB).
Cellular Protein Visualization
- Immunofluorescence microscopy is a technique used for visualizing cellular proteins.
Organelle Interactome
- The organelle interactome refers to the network of interactions between different organelles in a cell, and its main function is to facilitate cellular communication and regulation.
