Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs …
Enzymes are proteins made of amino acids. The functional group of each constituent amino acid catalyzes a wide variety of chemical reactions via ionic …
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand …
Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, …
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell …
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical …
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures …
Cells sense and respond to physical cues in their environment by converting mechanical stimuli into biochemically-detectable signals in a process called …
Numerous intracellular proteins physically interact in accordance with their intracellular and extracellular circumstances. Indeed, cellular functions …
