New publication in PNAS describing the tripartite cytotoxin MakABE from V. cholerae
In this paper the crystal structures of MakA, MakB and MakE are characterized. They are proteins that are secreted via the bacterial flagellum. Together they form a tripartite toxin that lyses erythrocytes and is cytotoxic to cultured human cells. The work was lead by group Karina Persson.
New publication describing the amyloid structure of human transthyretin
We have a new publication out in Nature communications describing the cryo-EM structure of the 2-protofilament fiber of human transthyretin. The fibers we purified from vitreous body material collected by vitrectomy from the eye of a Swedish carrier of the ATTR Val30Met variant.
