Scientific Data Images for Recombinant A. Muciniphila M60 domain-containing peptidase

Recombinant A. Muciniphila M60 domain-containing peptidase His-tag Protein Enzyme Activity Diagram.

Recombinant A. Muciniphila M60 domain-containing peptidase His-tag Protein (Cat # 11479-M6) cleaves glycoproteins N-terminally to glycosylated Ser/Thr residues that are near but not next to the cleavage residue. Specificity requires two adjacent truncated O-glycans and M60 peptidase cleaves between the two residues. * represents the residue for which M60 peptidase has recognition. Sialyated glycan substrates in diagram are less preferred.

Background: muciniphila M60 domain-containing

Recombinant A. Muciniphila M60 domain-containing peptidase (Am M60 peptidase), also referred to as AM0627, is a zinc-dependent mucin-targeting protease from Akkermansia muciniphila, a gut symbiont found within the human and mouse gut mucus layer. Am M60 peptidase is classified as an enzyme within the large M60-like family of metalloproteases containing gluzincin motifs from organisms known to inhabit mucosal host environments (1,2). Am M60 peptidase is a secreted, monomeric protein with a signal sequence, an immunoglobulin-like fold domain, and catalytic domain that contains the zinc-binding site within the gluzincin motif (2,3). Am M60 peptidase is capable of cleaving glycopeptides between adjacent O-glycosylated threonine or serine, with a preference towards desialylated substrates (4). Glycopeptides with adjacent non-physiological truncated O-glycan structure that promote tumorigenesis and metastasis, known as tumor-associated carbohydrate antigens, serve as optimal substrates for Am M60 peptidase (3,5). A. muciniphilia relies on host-derived mucin as an energy source and leads to production of short chain fatty acids (SCFA) via mucin-degradation byproducts. SCFA regulate inflammation and provide hosts with health benefits for diseases such as inflammatory bowel disease, obesity, autism, and cancer (2, 6-9). Mucin-degrading enzymes such as Am M60 peptidase play a prominent role in host mucin degradation and consequently Am M60 peptidase may be of interest as a therapeutic target, a diagnostic tool to detect and monitor disease progression, and/or useful as a tool to further study mucins and O-glycoproteins (2-4, 10).
