Co-Folding of a FliF-FliG Split Domain Forms the Basis of the MS:C Ring Interface within the Bacterial Flagellar Motor
Michael J. Lynch,Robert Levenson,Eun A Kim,Ria Sircar,David F. Blair,Frederick W. Dahlquist,Brian R. Crane +6 more
TL;DR: Modeling the FliFC:FliGN complex into cryo-electron microscopy rotor density updates the architecture of the middle and upper switch complex and shows how domain shuffling of a conserved interaction module anchors the cytoplasmic rotor to the membrane.

Cyclable Condensation and Hierarchical Assembly of Metastable Reflectin Proteins, the Drivers of Tunable Biophotonics.
TL;DR: It is shown that reversible titration of the excess positive charges of the reflectins, comparable with that produced by phosphorylation, is sufficient to drive the reversible condensation and hierarchical assembly of these proteins.

Structural insights into the interaction between the bacterial flagellar motor proteins FliF and FliG.
TL;DR: This work isolates and characterize the interaction between the N-terminal domain of Thermotoga maritima FliG (FliG(N)) and peptides corresponding to the conserved C-terminAL portion of T. maritime FliF, and proposes that the primary interaction site for Flif(C) is located on a conserved hydrophobic patch centered along helix 1 of Flig(N).
Molecular mechanism of reflectin’s tunable biophotonic control: Opportunities and limitations for new optoelectronics
TL;DR: In this article, it was shown that reflectin proteins fill the dynamically tunable Bragg lamellae in the reflective skin cells of certain squids, and that the reflectins function as a signal-controlled molecular machine, regulating an osmotic motor that tunes the thickness, spacing, and refractive index of the tunable, membrane-bound Bragg lambs in the iridocytes of the loliginid squids.

Reflectin Proteins Bind and Reorganize Synthetic Phospholipid Vesicles
Junyi Song,Robert Levenson,Jerome Santos,Lourdes Velazquez,Fan Zhang,Deborah Kuchnir Fygenson,Wenjian Wu,Daniel E. Morse +7 more
TL;DR: Analysis of the interactions of two purified reflectins with synthetic phospholipid membrane vesicles similar in composition to cellular membranes suggests specific reflectin-membrane interactions may play a role in the ontogenetic formation, long-term maintenance and/or dynamic behavior of their biophotonically active host membrane nanostructures.
