Mannan-binding Lectin-associated Serine Protease-2
Mannan-binding lectin-associated serine protease-2 (, ''MASP-2'', ''MASP2'', ''MBP-associated serine protease-2'', ''mannose-binding lectin-associated serine protease-2'', ''p100'', ''mannan-binding lectin-associated serine peptidase 2'') is an enzyme. This enzyme catalysis, catalyses the following chemical reaction : Selective cleavage after Arg223 in complement component C2 (-Ser-Leu-Gly-Arg-Lys-Ile-Gln-Ile) and after Arg76 in complement component C4 (-Gly-Leu-Gln-Arg-Ala-Leu-Glu-Ile) This Mannan (polysaccharide), mannan-binding lectin (MBL) recognizes patterns of neutral carbohydrates, such as mannose and N-acetylglucosamine.

Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...
