EC 3.4.22.29

Accepted name: picornain 2A

Reaction: Selective cleavage of TyrGly bond in picornavirus polyprotein

Other names: picornavirus endopeptidase 2A; poliovirus protease 2A; rhinovirus protease 2A; 2A protease; 2A proteinase; protease 2A; proteinase 2Apro; picornaviral 2A proteinase; Y-G proteinase 2A; poliovirus proteinase 2A; poliovirus protease 2Apro; picornaviral 2A proteinase

Comments: From entero-, rhino-, aphto- and cardioviruses. Smaller than the homologous picornain 3C, which is also in peptidase family C3 (picornain 3C family)
