Shweta Patro General Biology I Laboratory – Dr.Weber Due 9/25/09 RasMol Tutorial – CAP (Catabolite Activator Protein) A. Research and download protein of interest: CAP 1) Go to site 2) Read the following info The CAP is a protein It is normally found in bacterial cells It is found in the cytoplasm (because bacteria do not have a nucleus) The main function of CAP is to stimulate synthesis of the enzymes that break down non-glucose food molecules (change of metabolism) It performs its function by binding to DNA and regulates the transcription of proteins that digest glucose (down-regulates proteins that digest glucose and up-regulates ones that don’t) The CAP’s unique conformation (which is altered by cyclic AMP) allows it to bend DNA in a 90 degree angle. The structure of CAP also allows it to lure RNA polymerase close by so that transcription of glucose-digesting proteins can be regulated. 3)
