Summary for family C107

Family type peptidaseC107.001 - alphamesonivirus 3C-like peptidase (Cavally virus), MEROPS Accession MER0592262 (peptidase unit: 1387-1700)
Content of familyFamily C107 contains polyprotein processing cysteine endopeptidases.
History Identifier created: MEROPS 10.0 (14 Mar 2016)
Family C107 includes the alphamesonivirus 3C-like peptidase. Mesoviruses, such as Cavally virus, are insect RNA virus related to, but divergent from, nidoviruses. The Merovirus RNA encodes two polyproteins, known as pp1a and pp1ab, from which structural and non-structural proteins are generated by proteolytic cleavage (Blanck et al., 2014).
Catalytic typeCysteine
Active site residuesH1434 C1539 
Active siteThe active site dyad has been identified by site directed mutagenesis to be His, Cys (Blanck et al., 2014).
Activities and specificitiesThe 3C-like peptidases has a preference for Asn in P2 and cleaves the polyprotein at two sites (Blanck et al., 2014).
Molecular structureNo tertiary structures have been solved. From the order of the active site residues, family C107 is assumed to be a member of subclan PA(C) and the peptidase to have a chymotrypsin-like fold.
