Abstract: "De novo disulfide bond generation in the E. coli periplasm involves a transient complex consisting of DsbA, DsbB and ubiquinone. We present a structural model of the disulfide bond generating membrane protein DsbB in the lipid bilayers through a molecular dynamics simulation.

The starting PDB structure is calculated in Xplor-NIH using both X-ray reflections and SSNMR distance and dihedral angle restraints. The protein was then placed in a native-like membrane environment and went through solvation, minimization and equilibration. The model reveals the membrane topology of DsbB, which is consistent with our SSNMR observations of water or lipid to protein correlations from selective proton spin diffusion experiments."

06/01/11 - Rienstra Group Undergraduate Research Assistants: Aranee, Shin and Lars, were honored this year by the Chemistry and Biochemistry Departments:

Shin Wook Lee has spent the past two years in the Rienstra group producing alpha-synuclein protein with many different isotopic labeling patterns, all for SSNMR studies to determine the structure of the synuclein fibrils. For his senior thesis project, he then constructed cysteine mutants of alpha-synuclein and modified the protein by attaching spin labels at the cysteine positions. Shin graduates this year with top honors having earned the John C. Bailar Award for the best senior thesis in Chemistry at UIUC. Congratulations Shin!

Lars Rikardsen began working in the Rienstra lab in May 2009 with a project to express, purify, and crystallize isotopically-labeled CcR55 for SSNMR. Over the past few years, he has also worked with alpha-synuclein, expression and purification of DsbA and DsbB, and a range of other projects. Lars graduates this year with top honors having earned the R.C. Fusion Award given to the Chemistry graduate with the highest GPA. Lars was also receipient of the Robert H. Doremus Scholarship the previous year to support his research in the Rienstra Group. Congratulations Lars!

Aranee Sivananthan has been developing an HPLC-based activity assay for an iron-containing quinone monooxygenase, a project that requires synthesis of the enzyme's substrate. Aranee was recently honored with the William T. and Lynn Jackson Scholar Award, a $1500 prize to aid in her biochemistry-related research project. Aranee will spend one more year in the Rienstra Group before she graduates, afterwhich she's planning to pursue a career in medicine. Congratulations Aranee!

07/10/10 - Lindsay, Luisel, Mary, Mike And Kristin Help Organize and Participate In the Bonding with Chemistry Day Camp for Girls:

[The day camp, presented by the East Central Illinois Women Chemists Committee, first began in 2008 with a grant from the American Chemical Society and aims to encourage middle school girls from around Illinois to develop an interest in science, said Lindsay Sperling, graduate student in chemistry and day camp coordinator. Sperling said around 40 to 50 girls come to the University from area schools and the Chicago area for a day of basic hands-on chemistry experiments. Notices were sent out to schools earlier this year, and the committee also advertised the event to University faculty members with children. "Interest has also been spread through word-of-mouth," Sperling added. "People last year who had fun tell others about it, and they come to participate this year."] - Taken from the Daily Illini

05/13/10 - "Supramolecular protein structure determination by site-specific long-range intermolecular solid state NMR spectroscopy", Nieuwkoop, A. J..; Rienstra C. M. J. Am. Chem. Soc., 2010, 132(22), 7570-7571. (Published online, May 13, 2010):

We demonstrate that 3D Z-filtered TEDOR experiments, when performed on mixtures of isotopically labeled protein samples, report on site-specific intermolecular distance restraints. These data sets can be leveraged to perform rigorous structure calculations of the protein interface. In the example demonstrated here, we determine the packing arrangement of our nanocrystalline GB1 preparation to be consistent with the trigonal form as determined by X-ray diffraction. This represents an important proof of principle, in a case where the results can be directly compared with other structural information. We envision the application of this approach to determining the registry and quaternary arrangement of protein fibrils, which most often cannot be determined by diffraction methods.
 

05/04/10 - "NMR Determination of Protein pKa Values in the Solid State", Frericks Schmidt, H. L.; Shah, G. J.; Sperling, L. J.; Rienstra, C. M. J. Phys. Chem. Lett., 2010, 1, 1623-1628. (Published online, May 4, 2010):

Charged residues play an important role in defining key mechanistic features in many biomolecules. Determining the pKa values of large, membrane, or fibrillar proteins can be challenging with traditional methods. In this study we show how solid-state NMR is used to monitor chemical shift changes during a pH titration for the small soluble β1 immunoglobulin binding domain of protein G. The chemical shifts of all the amino acids with charged side-chains throughout the uniformly 13C,15N-labeled protein were monitored over several samples varying in pH; pKa values were determined from these shifts for E27, D36, and E42, and the bounds for the pKa of other acidic side-chain resonances were determined. Additionally, this study shows how the calculated pKa values give insights into the crystal packing of the protein.
 

04/16/10 - Rienstra Group members Ming, Lindsay, Gemma, Andy and Prof. Rienstra leave for the 51ST Experimental NMR Conference (ENC):
