Further Studies with Isolated Absolute Infrared Spectra of Bacteriorhodopsin Photocycle Intermediates: Conformational Changes and Possible Role of a New Proton-Binding Center

January 1, 2013
Author(s)
Richard W. Hendler, Curtis W. Meuse, Paul Smith, John W. Kakareka
We recently published procedures describing the isolation of absolute infrared spectra for the intermediates of the bacteriorhodopsin (BR) photocycle and from these, obtaining transitional difference spectra between consecutive intermediates. In that work

Revision of the SNPforID 34-plex forensic ancestry test: Assay enhancements, standard reference sample genotypes and extended population studies

January 1, 2013
Author(s)
John Butler, Manuel Fondevila, Carla Santos, Ana Freire, Christopher Phillips, M Lareu, Peter Vallone, A. Carracedo
A revision of an established 34 SNP forensic ancestry test has been made by swapping the under- performing rs727811 component SNP with the highly informative rs3827760 that shows a near-fixed East Asian specific allele. We collated SNP variability data for

Identification and Quantification of Human DNA Repair Protein NEIL1 by Liquid Chromatography/Isotope-Dilution Tandem Mass Spectrometry

December 26, 2012

M Miral Dizdar, Pawel Jaruga, Guldal Kirkali, Bryant C. Nelson, Gamze Tuna, Prasad T. Reddy
Accumulated evidence points to DNA repair capacity as an important factor in cancer and other diseases. DNA repair proteins are promising drug targets and are emerging as prognostic and therapeutic biomarkers. Thus, the knowledge of the overexpression or

Structure and Activity of PA5508, a Novel Hexameric Glutamine Synthase Homolog

December 12, 2012
Author(s)
Jane E. Ladner, James F. Parsons
The structure of PA5508 from Pseudomonas aeruginosa, a glutamine synthase (GS) homolog, has been solved at 2.5 Å. Surprisingly, PA5508 forms single hexameric rings rather than the stacked double rings that are characteristic of GS. The C-terminal helical

The Effects of Diffusion on an Exonuclease/Nanopore-Based DNA Sequencing Engine

December 7, 2012
Author(s)
Joseph E. Reiner, Joseph W. Robertson, Arvind Balijepalli, Daniel L. Burden, Bryon S. Drown, John J. Kasianowicz
The ability to electronically detect and characterize individual polynucleotides as they are driven through a single protein ion channel may eventually prove useful for rapidly sequencing DNA (base-by-base) in a ticker tape-like fashion. More recently, a

Relative Rigidity of Cell-Substrate Affects Hepatic and Hepatocellular Carcinoma Cell Migration

December 3, 2012
Author(s)
Martin Y. Chiang, Hongbing Wang, Li Zhong, Qiaoyan Tan, Gurinder K. Singh, Song Li, Li Yang, Yanzi Yangben
Polyacrylamide gels with different stiffness and glass were employed as substrates to investigate how substrate stiffness affects the cellular stiffness of adherent hepatocellular carcinoma (HCCLM3) and hepatic (L02) cells. The interaction of how cell
