Summary for clan SS
| History | MEROPS 7.2 (14 October 2005) |
| Description | Serine nucleophile; catalytic residues in the order Ser, Glu, His |
| Contents of clan | Clan SS contains enzymes that cleave amide bonds between L- and D-amino acids that occur in bacterial peptidoglycan. |
| Evidence | The structure of the type peptidase of family S66 is unlike that known for any other peptidase (Korza & Bochtler, 2005). |
| Catalytic mechanism | (See family S66.) |
| Peptidase activity | (See family S66.) |
| Protein fold | See Korza & Bochtler (2005)). |
| Homologous non-peptidase families | Proteins with similar folds, detected by querying the DALI server, are the biological subunit of l-fucose isomerase from Escherichia coli and the hypothetical protein MJ0783 from Methanocaldococcus jannaschii. |
