CC -!- FUNCTION: Inhibits thermolysin, bacillolysin and pseudolysin, CC B.polymyxa metalloprotease and human MMP1 and MMP3. No activity on CC trypsin or cysteine protease papain. {ECO:0000269|PubMed:15115439, CC ECO:0000269|PubMed:9738891}. CC -!- INDUCTION: During humoral immune response. By lipopolysaccharide (LPS). CC {ECO:0000269|PubMed:15115439, ECO:0000269|PubMed:9738891}. CC -!- PTM: Cleaved. {ECO:0000305}. CC -!- PTM: Five disulfide bonds are present. When artificially cleaved by CC thermolysin between Asn-56 and Ile-57, the two obtained chains (called CC heavy and light chains) remain linked. CC -!- PTM: The N-terminus is blocked.
