Protein

Membrane metallo-endopeptidase-like 1

Gene

MMEL1

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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).By similarity

Catalytic activityi

Preferential cleavage of polypeptides between hydrophobic residues, particularly with Phe or Tyr at P1'.

Cofactori

Binds 1 zinc ion per subunit.By similarity

Enzyme regulationi

Inhibited by thiorphan and phosphoramidon.By similarity
