Domain Architecture (Details)
InterPro domains unassigned to SynO:
Peptidases are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry. Families are grouped by their catalytic type.he first character representing the catalytic type: A.spartic; C.ysteine; G.lutamic acid; M.etallo; S.erine; T.hreonine; and U.nknown. A clan that contains families of more than one type is described as being of type P. The serine.hreonine and cysteine peptidases utilise the catalytic part of an amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic.lutamic and metallopeptidases.he nucleophile is an activated water molecule. Cysteine peptidases have characteristic molecular topologies.hich can be seen not only in their three-dimensional structures.ut commonly also in the two-dimensional structures. The peptidase domain is responsible for peptide bond hydrolysis; in Merops this is termed the peptidase unit. These are peptidases in which the nucleophile is the sulphydryl group of a cysteine residue. Cysteine proteases are divided into clans (proteins which are evolutionary related).nd further sub-divided into families.n the basis of the architecture of their catalytic dyad or triad : Clan CA contains the families of papain (C1).alpain (C2).treptopain (C10) and the ubiquitin-specific peptidases (C12.19).s well as many families of viral cysteine endopeptidases. Clan CD contains the families of clostripain (C11).ingipain R (C25).egumain (C13).aspase-1 (C14) and separin (C50). These enzymes have specificities dominated by the interactions of the S1 subsite. Clan CE contains the families of adenain (C5) from adenoviruses.he eukaryotic Ulp1 protease (C48) and the bacterial YopJ proteases (C55). Clan CF contains only pyroglutamyl peptidase I (C15). Clan PA contains the picornains (C3).hich have probably evolved from serine peptidases and which form the majority of enzymes in this clan. Clans PB and CH contain the autolytic cysteine peptidases. This group of cysteine peptidases belong to MEROPS peptidase family C50 (separase family.lan CD). The active site residues for members of this family and family C14 occur in the same order in the sequence: H..The separases are caspase-like proteases.hich plays a central role in the chromosome segregation. In yeast they cleave the rad21 subunit of the cohesin complex at the onset of anaphase. During most of the cell cycle.eparase is inactivated by the securin/cut2 protein.hich probably covers its active site.

Local Annotation
Synapse Ontology
A process that increases short-term neuronal synaptic plasticity, the ability of neuronal synapses to change in the short-term as circumstances require. Short-term neuronal synaptic plasticity generally involves increasing or decreasing synaptic sensitivity.
