EC 3.4.21.90     
Accepted name: togavirin
Reaction: Autocatalytic release of the core protein from the N-terminus of the togavirus structural polyprotein by hydrolysis of a -Trp┼Ser- bond
Other name(s): Sindbis virus protease; Sindbis virus core protein; NsP2 proteinase
Comments: Known from the Sindbis and Semliki forest togaviruses. Once released, the core protein does not retain catalytic activity. Togavirin is the type example of peptidase family S3 and has a similar tertiary structure to chymotrypsin [3]
