A disintegrin and metalloproteinase with thrombospondin motifs 5 also known as ADAMTS5 is an enzyme that in humans is encoded by the ADAMTS5 gene.
ADAMTS13 —also known as von Willebrand factor-cleaving protease (VWFCP)—is a zinc-containing metalloprotease enzyme that cleaves von Willebrand factor (vWf), a large protein involved in blood clotting. It is secreted into the blood and degrades large vWf multimers, decreasing their activity.
A disintegrin and metalloproteinase with thrombospondin motifs 2 (ADAM-TS2) also known as procollagen I N-proteinase is an enzyme that in humans is encoded by the ADAMTS2 gene.
Membrane-type matrix metalloproteinase-1 is an enzyme. This enzyme catalyses the following chemical reaction
Aspartic proteases are a catalytic type of protease enzymes that use an activated water molecule bound to one or more aspartate residues for catalysis of their peptide substrates. In general, they have two highly conserved aspartates in the active site and are optimally active at acidic pH. Nearly all known aspartyl proteases are inhibited by pepstatin.
Aggrecan (ACAN), also known as cartilage-specific proteoglycan core protein (CSPCP) or chondroitin sulfate proteoglycan 1, is a protein that in humans is encoded by the ACAN gene. This gene is a member of the lectican (chondroitin sulfate proteoglycan) family. The encoded protein is an integral part of the extracellular matrix in cartilagenous tissue and it withstands compression in cartilage.
Prolyl endopeptidase (PE) also known as prolyl oligopeptidase or post-proline cleaving enzyme is an enzyme that in humans is encoded by the PREP gene.
Lysins, also known as endolysins or murein hydrolases, are hydrolytic enzymes produced by bacteriophages in order to cleave the host's cell wall during the final stage of the lytic cycle. Lysins are highly evolved enzymes that are able to target one of the five bonds in peptidoglycan (murein), the main component of bacterial cell walls, which allows the release of progeny virions from the lysed cell. Cell-wall-containing Archaea are also lysed by specialized pseudomurein-cleaving lysins, while most archaeal viruses employ alternative mechanisms. Similarly, not all bacteriophages synthesize lysins: some small single-stranded DNA and RNA phages produce membrane proteins that activate the host's autolytic mechanisms such as autolysins.
Aggrecanases are extracellular proteolytic enzymes that are members of the ADAMTS family. Aggrecanases act on large proteoglycans known as aggrecans, which are components of connective tissues such as cartilage. The inappropriate activity of aggrecanase is a mechanism by which cartilage degradation occurs in diseases such as arthritis. At least two forms of aggrecanase exist in humans: ADAMTS4 or aggrecanase-1 and ADAMTS5 or aggrecanase-2. Both proteins contain thrombospondin (TS) motifs required for proper recognition of substrates. Although both proteins can cleave the substrate aggrecan at the same position, they differ in kinetics and in secondary cleavage sites.
A disintegrin and metalloproteinase with thrombospondin motifs 4 is an enzyme that in humans is encoded by the ADAMTS4 gene.
Membrane-bound transcription factor site-2 protease, also known as S2P endopeptidase or site-2 protease (S2P), is an enzyme encoded by the MBTPS2 gene which liberates the N-terminal fragment of sterol regulatory element-binding protein (SREBP) transcription factors from membranes. S2P cleaves the transmembrane domain of SREPB, making it a member of the class of intramembrane proteases.
A disintegrin and metalloproteinase with thrombospondin motifs 1 is an enzyme that in humans is encoded by the ADAMTS1 gene.
Matrix metalloproteinase-19 (MMP-19) also known as matrix metalloproteinase RASI is an enzyme that in humans is encoded by the MMP19 gene.
A disintegrin and metalloproteinase with thrombospondin motifs 8 is an enzyme that in humans is encoded by the ADAMTS8 gene.
A disintegrin and metalloproteinase with thrombospondin motifs 3 is an enzyme that in humans is encoded by the ADAMTS3 gene. The protein encoded by this gene is the major procollagen II N-propeptidase.
Neutrophil collagenase, also known as matrix metalloproteinase-8 (MMP-8) or PMNL collagenase (MNL-CL), is a collagen cleaving enzyme which is present in the connective tissue of most mammals. In humans, the MMP-8 protein is encoded by the MMP8 gene. The gene is part of a cluster of MMP genes which localize to chromosome 11q22.3. Most MMP's are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. However, the enzyme encoded by this gene is stored in secondary granules within neutrophils and is activated by autolytic cleavage.

Amanda Jane Fosang is a biomedical researcher who has pioneered arthritis research in Australia.
Asparagine endopeptidase is a proteolytic enzyme from C13 peptidase family which hydrolyses a peptide bond using the thiol group of a cysteine residue as a nucleophile. It is also known as asparaginyl endopeptidase, citvac, proteinase B, hemoglobinase, PRSC1 gene product or LGMN, vicilin peptidohydrolase and bean endopeptidase. In humans it is encoded by the LGMN gene.
