From chaperones to the membrane with a BAM!

AM Plummer, KG Fleming - Trends in biochemical sciences, 2016 - cell.com
Outer membrane proteins (OMPs) play a central role in the integrity of the outer membrane
of Gram-negative bacteria. Unfolded OMPs (uOMPs) transit across the periplasm, and …

The process of folding proteins into membranes: challenges and progress

AM Stanley, KG Fleming - Archives of biochemistry and biophysics, 2008 - Elsevier
Just 25years ago the Anfinsen thermodynamic hypothesis was shown to be valid for
membrane proteins. Despite the complex biological machinery required for their in vivo …

2019 Canadian guideline for physical activity throughout pregnancy

MF Mottola, MH Davenport, SM Ruchat… - British journal of sports …, 2018 - bjsm.bmj.com
The objective is to provide guidance for pregnant women and obstetric care and exercise
professionals on prenatal physical activity. The outcomes evaluated were maternal, fetal or …

Energetics of membrane protein folding

KG Fleming - Annual review of biophysics, 2014 - annualreviews.org
Fundamental to the central goals of structural biology is knowledge of the energetics of
molecular interactions. Because membrane proteins reside in a free energy minimum …

Side-chain hydrophobicity scale derived from transmembrane protein folding into lipid bilayers

CP Moon, KG Fleming - Proceedings of the National …, 2011 - National Acad Sciences
The transfer free energies of the twenty natural amino acid side chains from water to
phospholipid bilayers make a major contribution to the assembly and function of membrane …

What makes a protein a protein? Hydrophobic core designs that specify stability and structural properties

M Munson, S Balasubramanian, KG Fleming… - Protein …, 1996 - Wiley Online Library
Here we describe how the systematic redesign of a protein's hydrophobic core alters its
structure and stability. We have repacked the hydrophobic core of the four‐helix‐bundle …

[HTML][HTML] β-Barrel proteins that reside in the Escherichia coli outer membrane in vivo demonstrate varied folding behavior in vitro

NK Burgess, TP Dao, AM Stanley… - Journal of Biological …, 2008 - ASBMB
Little is known about the dynamic process of membrane protein folding, and few models
exist to explore it. In this study we doubled the number of Escherichia coli outer membrane …

[HTML][HTML] The effect of point mutations on the free energy of transmembrane α-helix dimerization

KG Fleming, AL Ackerman, DM Engelman - Journal of molecular biology, 1997 - Elsevier
Glycophorin A forms homodimers through interaction of the single, helical transmembrane
domains of the monomers. The dimers are stable in sodium dodecylsulfate (SDS), permitting …

Outer membrane β-barrel protein folding is physically controlled by periplasmic lipid head groups and BamA

D Gessmann, YH Chung, EJ Danoff… - Proceedings of the …, 2014 - National Acad Sciences
Outer membrane β-barrel proteins (OMPs) are crucial for numerous cellular processes in
prokaryotes and eukaryotes. Despite extensive studies on OMP biogenesis, it is unclear why …

[PDF][PDF] E. coli outer membrane and interactions with OmpLA

EL Wu, PJ Fleming, MS Yeom, G Widmalm, JB Klauda… - Biophysical journal, 2014 - cell.com
