Cytosolic carboxypeptidase N-terminal domain
This entry corresponds to the N-terminal domain of cytosolic carboxypeptidases. The N-terminal domain folds into a nine-stranded antiparallel beta sandwich. This domain is specific to CCP proteins and is absent in other carboxypeptidases. It has been hypothesized that the N-terminal domain might contribute to folding, might have a regulatory function and/or might be involved in binding other proteins.
