An integrative structural and biophysical workflow indicates engagement of VRC01 germline antibodies can occur with a gp120 426c core construct containing all wild-type N-linked glycosylation sites, including the Asn276 glycan.
Probing the DNA motor SpoIIIE at the single-molecule level has revealed its force-generating step, rich translocation dynamics during motor operation and a novel, bi-phasic mechanical response to opposing force.
A correlation between the periplasmic embellishment of the flagellar motor and its stator system type is described, motors with dual H+-dependent stator systems have one periplasmic ring formed by MotY.
Aβ inhibitors effectively block its aggregation, while also reducing seeding of tau aggregation from Aβ, tau, and AD derived fibrils, suggesting the two share a structurally related disease relevant interface.
Atomic structures of hIAPP fibrillar segments, determined using the cryo electron microscopy method MicroED, reveal that strong, stable intermolecular interactions are important features of cytotoxic amyloid proteins.
