The Crystal Structure of Human α(2) -Macroglobulin Reveals a Unique Molecular Cage

Research output: Contribution to journal/Conference contribution in journal/Contribution to newspaperJournal articleResearchpeer-review

I'm your Venus: The crystal structure of the human methylamine-induced form of α(2) -macroglobulin (α(2) M) shows its large central cavity can accommodate two medium-sized proteinases (see structure, front part clipped off to better show central cavity). Twelve major entrances provide access for small substrates to the cavity and the still-active trapped "prey". The structure unveils the molecular basis of the unique "venus flytrap" mechanism of α(2) M.
