Ubiquitin
Description
"Ubiquitin Is A Small (8.5 Kda) Regulatory Protein That Has Been Found In Almost All Tissues (Ubiquitously) Of Eukaryotic Organisms. Ubiquitination Is A Post Translational Modification (An Addition To A Protein After It Has Been Made) Where Ubiquitin Is Attached To A Substrate Protein." Http://En.Wikipedia.Org/Wiki/Ubiquitin The Addition Of Ubiquitin To Proteins Can Signal For Their Degradation Via The Proteasome. This Model Is Based On Human Erythrocytic Ubiquitin. The C-Terminal Glycine Residue, Conjugated To The Lysine Residues Of Target Proteins, Is Represented As Spheres.
