KEGG   ENZYME: 3.4.21.97
Entry
EC 3.4.21.97                Enzyme                                 
Name
assemblin
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Serine endopeptidases
Reaction(IUBMB)
Cleaves -Ala!Ser- and -Ala!Ala- bonds in the scaffold protein
Comment
Involved in the breakdown of the scaffold protein during the late stages of assembly of the herpes-virus virion. Inhibited by diisopropyl fluorophosphate. Type example of peptidase family S21. Catalytic residues are His, Ser, His, a combination not known for any other peptidase, and the protein fold also is unique. Known from herpes viruses of several types, cytomegalovirus, Epstein-Barr virus and human herpesvirus 3
