Construction of exact minimal parking garages: nonlinear helical motifs in optimally packed lamellar structures [PDF]
Proc. R. Soc. A 477 (2021) 20200891, 2020 Minimal surfaces arise as energy minimizers for fluid membranes and are thus found in a variety of biological systems. The tight lamellar structures of the endoplasmic reticulum and plant thylakoids are composed of such minimal surfaces in which right and left handed helical motifs are embedded in stoichiometry suggesting global pitch balance.

New insights into the Tat protein transport cycle from characterizing the assembled Tat translocon
Molecular Microbiology, Volume 118, Issue 6, Page 637-651, December 2022., 2022 The Tat translocon transports folded proteins via a unique and enigmatic mechanism. The translocon assembles transiently, only in the presence of a substrate, a protonmotive force, and only at native expression levels, and for this reason is exceedingly difficult to access experimentally.

The Role of Periodic Structures in Light Harvesting
Plants, 2021 The features of light propagation in plant leaves depend on the long-period ordering in chloroplasts and the spectral characteristics of pigments. This work demonstrates a method of determining the hidden ordered structure. Transmission spectra have been

Dehydrins (LTI29, LTI30, COR47) from Arabidopsis thaliana expressed in Escherichia coli protect Thylakoid membrane during freezing [PDF]
Journal of the Serbian Chemical Society, 2013 As the name dehydrins implies, these proteins are typically expressed in response to dehydration which can be caused by drought, osmotic stress or freezing temperatures 1. In general, dehydrins occur in plants as multi-gene families.
