| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Metalloprotease involved in sperm function, possibly by modulating the processes of fertilization and early embryonic development. Degrades a broad variety of small peptides with a preference for peptides shorter than 3 kDa containing neutral bulky aliphatic or aromatic amino acid residues. Shares the same substrate specificity with MME and cleaves peptides at the same amide bond By similarity. |
| Catalytic activity | Preferential cleavage of polypeptides between hydrophobic residues, particularly with Phe or Tyr at P1'. |
| Cofactor | Binds 1 zinc ion per subunit By similarity. |
| Enzyme regulation | Inhibited by thiorphan and phosphoramidon. |
| Subcellular location | Membrane; Single-pass type II membrane protein. Secreted. Note: A secreted form produced by proteollytic cleavage also exists Probable. |
| Tissue specificity | Specifically expressed in testis and central nervous system (CNS) (at protein level). Restricted to developing and differentiating fields of the CNS. The soluble form is expressed in round spermatides. Ref.1 Ref.4 |
| Post-translational modification | N-glycosylated. Ref.6 |
| Sequence similarities | Belongs to the peptidase M13 family. |
| Biophysicochemical properties | Kinetic parameters: KM=62 µM for Tyrosyl-D-Ala(2)-Leu(5)-enkephalin Ref.5 Ref.6 KM=27 µM for Suc-AA-F-AMC (Membrane metallo-endopeptidase-like 1) KM=50 µM for Suc-AA-F-AMC (Membrane metallo-endopeptidase-like 1, soluble form) KM=40 µM for Suc-AA-V-AMC (Membrane metallo-endopeptidase-like 1) KM=100 µM for Suc-AA-V-AMC (Membrane metallo-endopeptidase-like 1, soluble form) KM=23 µM for Suc-G-LF-AMC (Membrane metallo-endopeptidase-like 1) KM=35 µM for Suc-G-LF-AMC (Membrane metallo-endopeptidase-like 1, soluble form) |
