Hydrolases;
Acting on peptide bonds (peptidases);
Serine endopeptidases
Reaction(IUBMB)
Autocatalytic release of the core protein from the N-terminus of the togavirus structural polyprotein by hydrolysis of a -Trp!Ser- bond
Comment
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]
