Name  Peptidase C21 Short Name  Peptidase_C21
Type  Domain 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 []. This entry is found in cysteine peptidases belong to the MEROPS peptidase family C21 (tymovirus endopeptidase family, clan CA). The type example is tymovirus endopeptidase (turnip yellow mosaic virus). The noncapsid protein expressed from ORF-206 of turnip yellow mosaic virus (TYMV) is autocatalytically processed by apapain-like protease, producing N-terminal 150kDa and C-terminal 70kDa proteins.
