Application
Peptidyl-L-lysine (-L-arginine) hydrolase
Use Carboxypeptidase B for the sequence analysis of proteins by successive cleavage of basic amino acids from the C-terminus of proteins.
Biochem/physiol Actions
Carboxypeptidase B is a Zn2+-metalloprotease, catalyzing the hydrolysis of the basic amino acids L-Lys and L-Arg from the C-terminal position in polypeptides.
