Thalassiosira pseudonana

Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.

Catalysis of the hydrolysis of N-terminal amino acid residues from in a polypeptide chain.

The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
