Destabilase-2 is documented mechanistically only; no human evidence. Reported fibrin-cleaving activity does NOT establish clinical thrombolytic efficacy, and no FDA-approved derivative exists.

Destabilase Isopeptidase Activity
Isopeptidase domain of destabilase that cleaves cross-linked fibrin — distinct from lysozyme domain.
