Keratin intermediate filaments: differences in the sequences of the Type I and Type II chains explain the origin of the stability of an enzyme-resistant four-chain fragment.

Journal of structural biology

Fraser RD, Parry DA.
PMID: 24384118
J Struct Biol. 2014 Mar;185(3):317-26. doi: 10.1016/j.jsb.2013.12.012. Epub 2013 Dec 30.

Previous studies have shown that a strong interaction exists between oppositely directed 1B molecular segments in the intermediate filaments of trichocyte keratins. A similar interaction has been identified as having a significant role in the formation of unit-length filaments,...

Reprint of "Generation of ribosome nascent chain complexes for structural and functional studies" [J. Struct. Biol. 158 (2007) 463-471].

Journal of structural biology

Schaffitzel C, Ban N.
PMID: 17660065
J Struct Biol. 2007 Aug;159(2):302-10. doi: 10.1016/S1047-8477(07)00167-0.

Biochemical and structural studies of co-translational folding, targeting and translocation depend on an efficient methodology to prepare ribosome nascent chain complexes (RNCs). Here we present our approach for the generation of homogenous and stable RNCs involving in vitro translation...

Reprint of "Three-dimensional elemental mapping of phosphorus by quantitative electron spectroscopic tomography (QuEST)" [J. Struct. Biol. 160 (2007) 35-48].

Journal of structural biology

Aronova MA, Kim YC, Harmon R, Sousa AA, Zhang G, Leapman RD.
PMID: 18342742
J Struct Biol. 2008 Mar;161(3):322-35. doi: 10.1016/S1047-8477(08)00062-2.

We describe the development of quantitative electron spectroscopic tomography (QuEST), which provides 3-D distributions of elements on a nanometer scale. Specifically, it is shown that QuEST can be applied to map the distribution of phosphorus in unstained sections of...

Reprint of "On the feasibility of visualizing ultrasmall gold labels in biological specimens by STEM tomography" [J. Struct. Biol. 159 (2007) 507-522].

Journal of structural biology

Sousa AA, Aronova MA, Kim YC, Dorward LM, Zhang G, Leapman RD.
PMID: 18342743
J Struct Biol. 2008 Mar;161(3):336-51. doi: 10.1016/S1047-8477(08)00063-4.

Labeling with heavy atom clusters attached to antibody fragments is an attractive technique for determining the 3D distribution of specific proteins in cells using electron tomography. However, the small size of the labels makes them very difficult to detect...

Practical performance evaluation of a 10k × 10k CCD for electron cryo-microscopy.

Journal of structural biology

Bammes BE, Rochat RH, Jakana J, Chiu W.
PMID: 21619932
J Struct Biol. 2011 Sep;175(3):384-93. doi: 10.1016/j.jsb.2011.05.012. Epub 2011 May 17.

Electron cryo-microscopy (cryo-EM) images are commonly collected using either charge-coupled devices (CCD) or photographic film. Both film and the current generation of 16 megapixel (4k × 4k) CCD cameras have yielded high-resolution structures. Yet, despite the many advantages of...

Contrast transfer function correction applied to cryo-electron tomography and sub-tomogram averaging.

Journal of structural biology

Zanetti G, Riches JD, Fuller SD, Briggs JA.
PMID: 19666126
J Struct Biol. 2009 Nov;168(2):305-12. doi: 10.1016/j.jsb.2009.08.002. Epub 2009 Aug 08.

Cryo-electron tomography together with averaging of sub-tomograms containing identical particles can reveal the structure of proteins or protein complexes in their native environment. The resolution of this technique is limited by the contrast transfer function (CTF) of the microscope....

The DNA-binding mechanism of the TCS response regulator ArlR from Staphylococcus aureus.

Journal of structural biology

Yan H, Wang Q, Teng M, Li X.
PMID: 31520693
J Struct Biol. 2019 Dec 01;208(3):107388. doi: 10.1016/j.jsb.2019.09.005. Epub 2019 Sep 11.

ArlRS is an essential two-component system in Staphylococcus aureus that regulates the transcription of virulence factors and participate in numerous pathogenic and symbiotic processes. In this work, we identified different DNA binding properties and oligomerization states among the DNA-binding...

3D mapping of native extracellular matrix reveals cellular responses to the microenvironment.

Journal of structural biology: X

Lansky Z, Mutsafi Y, Houben L, Ilani T, Armony G, Wolf SG, Fass D.
PMID: 32055794
J Struct Biol X. 2019 Jan-Mar;1:100002. doi: 10.1016/j.yjsbx.2018.100002.

Cells and extracellular matrix (ECM) are mutually interdependent: cells guide self-assembly of ECM precursors, and the resulting ECM architecture supports and instructs cells. Though bidirectional signaling between ECM and cells is fundamental to cell biology, it is challenging to...
