None.

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 [PMID: 11517925].

This group of cysteine peptidases belong to MEROPS peptidase family C28 (clan CA).The protein fold of the peptidase unit for members of this family resembles that of papain.

The leader peptidase of Foot-and-mouth disease virus cleaves itself from the growing polyprotein and also cleaves the host translation initiation factor 4GI (eIF4G), thus inhibiting 5'-cap dependent translation [PMID: 12297280].
