Name  Peptidase C26 Short Name  Peptidase_C26
Type  Family Description  Cysteine peptidases have characteristic molecular topologies, which can be seen not only in their three-dimensional structures, but commonly also in the two-dimensional structures. 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), and further sub-divided into families, on the basis of the architecture of their catalytic dyad or triad []. These peptidases have gamma-glutamyl hydrolase activity; that is they catalyse the cleavage of the gamma-glutamyl bond in poly-gamma-glutamyl substrates. They are structurally related to , but contain extensions in four loops and at the C terminus []. They belong to MEROPS peptidase family C26 (gamma-glutamyl hydrolase family), clan PC. The majority of the sequences are classified as unassigned peptidases.
