Deubiquitinases belong to the protease family. This family is divided into five classes, according to the nature of the amino acid composition of their active site carrying out the catalysis: serine protease, cysteine proteases, acid proteases, metalloproteases, threonine proteases. DUBs belong to only two of these families: metalloproteases and cysteine proteases. | Deubiquitinases belong to the protease family.

Among the cysteine proteins, four subfamilies can be described according to their catalytic domains: ubiquitin-specific proteases (USP), les Ubiquitin C-terminal hydrolases (UCH), Otubain proteases (OTU) and Machado-joseph disease proteases (MJD). The deubiquitinases belonging to the family of metalloproteases all have a JAMM catalytic domain (JAB1/MPN/Mov34 metalloenzyme). <ref>PMID:15571815</ref> | Among the cysteine proteins, four subfamilies can be described according to their catalytic domains: ubiquitin-specific proteases (USP), les Ubiquitin C-terminal hydrolases (UCH), Otubain proteases (OTU) and Machado-joseph disease proteases (MJD).

Within these two families, DUBs are classified into subfamilies according to the differences in their amino acid sequences surrounding the catalytically active amino acid residues. <ref>PMID:15571815</ref> | |||
