Ubiquitin By Mr. Szerminski Sample 4U CCT
General info: - it is a regulatory protein that has been found in almost all tissues of eukaryotes - one of its functions: it directs protein recycling - can attach to proteins and label them for destruction. - discovery won the Nobel Prize for chemistry in 2004 A specific journal article about new research: Current Alzheimer Research, 2010, 7, 549-555 Topics to be discussed
General Info • protein consists of 76 amino acids • molecular mass of about 8.5 kDa (8 500 g/mol) • key features: C-terminal tail and 7 lysine residues. • human and yeast ubiquitin share 96% sequence identity • one-letter code (lysine residues in bold):
How it Works • Works by protein post-translational modification (PTM) in which the carboxylic acid of the terminal glycine from the di-glycine motif forms an amide bond to the epsilon amine of the lysine in the modified protein.
Result Analysis (Conclusions) In simple language: Our (humanity’s) understanding the ubiquitin system is still in its infancy.
