Protasomes are protein complexes which degrade unneeded or damaged proteins by proteolysis, a chemical reaction that breaks peptide bonds. Proteins are tagged for degradation with a small protein called ubiquitin, and the tagging reaction is catalyzed by enzymes called ubiquitin ligases. ATP is required to activate ubiquitin in the first step of linking it to the target protein. 
The reaction is
Ubiquitin + E1.SH + ATP = Ub.S.E1 + AMP + PP

goldfiish [28.3K]

Answer is membrane protein

Plasma membrane or cell membrane is made of lipoprotein (lipid and protein). The structure of the plasma membrane is based on the fluid mosaic model which gives basic description of the structure and behavior of membranes. The plasma membrane is a mosaic of phospholipids, cholesterol and proteins. Many proteins can move within the plasma membrane through membrane diffusion.  The membrane proteins regulates the coming and going of substances into and out of the cell.
