      Can anyone help me to define Exopeptidase please? i hv look up the dictionary in this web but still i can’t find it …. This term appeared in my text book and said it is used to breakdown the TERMINAL peptide bond of a polypeptide , breakdown of terminal bond means amino acids can be fomed. So how is it differ from the dipeptidase then ? both of them hv the same function…?????.i am confused ><

      Please refer to rule #4. relevant title 🙂
      Exopeptidase – Any of a group of enzymes that catalyze the hydrolysis of single amino acids from the end of a polypeptide chain. (from an online dictionary)
      An endopeptidase catalyses the hydrolysis of single amino acids in the middle of a polypeptide chain.
      Doesnt a dipeptidase just catalyze the hydrolysis of dipeptides into the two amino acids.
      So no, i dont think they have the same function.
      TERMNAL just means the bond on the end. N-terminal and C-terminal.

      Chris4 is right. A dipeptidase breaks the bond between 2 aminos in a dipeptide, resulting 2 free amino acids
