Domaini

There are 3 carboxypeptidase domains. Only the first two domains have any catalytic activity. The first domain preferentially cleaves C-terminal Arg residues, whereas the second preferentially cleaves C-terminal Lys residues. The third domain binds to pre-S, hepatitis B virus large envelope protein.2 Publications

Sequence similaritiesi

Belongs to the peptidase M14 family.Sequence analysis

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
