Expression of recombinant mouse cytosolic carboxypeptidase 6 in Escherichia coli
Cytosolic carboxypeptidase 6 (CCP6) is a member of cytosolic carboxypeptidase (CCP) family that catalyze the removal of polyglutamate side chains from protein substrates. Biochemical and biophysical characterization of CCPs requires large quantities of purified proteins. However, no method describin...
