PPT-Chapter 8: Protein Regulation and Degradation

81 Isozymes Isozymes are enzymes that differ in amino acid sequence but catalyze the same chemical reaction Example Cyclooxygenase Enzymes Cox1 and Cox2 Example Cyclooxygenase Enzymes Cox1 and Cox2. The classic principle of . protein folding. is that all the information required for a protein to adopt the correct three-dimensional conformation is provided by its amino acid sequence..

Abstract. Myosin is a motor protein that has many different functions, including muscle contraction, cell transport, and cell adhesion. There are of course several different subtypes and isoforms of myosin proteins so the project will focus on a single type of myosin, non-muscle myosin II B (NM II B) in . Eukaryotic Gene Regulation.
