High-Resolution Crystal Structures of Erythrina Cristagalli Lectin in Complex With Lactose and 2'-a-L-Fucosyllactose and Correlation With Thermodynamic Binding Data

August 1, 2002
Author(s)
C Svensson, S Teneberg, C L. Nilsson, A Kjellberg, Frederick P. Schwarz, N Sharon, U Krengel
The primary sequence of Erythrina cristagalli lectin (ECL) was mapped by mass spectrometry, and the crystal structures of the lectin in complex with lactose and 2'-α-L-fucosyllactose were determined at 1.6 and 1.7 resolution, respectively. The two

Chorismate Lyase: Kinetics and Engineering for Stability

January 31, 2002

Marcia J. Holden, M P. Mayhew, David T. Gallagher, V L. Vilker
By removing the enolpyruvyl group from chorismate, chorismate lyase (CL) produces p-hydroxybenzoate (p-HB) for the ubiquinone biosynthetic pathway. We have analyzed CL by several spectroscopic and chemical techniques and measured its kinetic (k cat = 1.7x

Inferring the nominal molecular mass of an analyte from its electron ionization mass spectrum

August 23, 2023
Author(s)
Arun Moorthy, Anthony J. Kearsley, William Mallard, William E. Wallace, Stephen E. Stein
The performance of three algorithms for predicting nominal molecular mass from an analyte's electron ionization mass spectrum is presented. The Peak Interpretation Method (PIM) attempts to quantify the likelihood that a molecular ion peak is contained in

Long-term instability in UTC time links

January 31, 2017
Author(s)
Victor S. Zhang, Demetrios Matsakis, Zhiheng Jiang
Calibration and link stability are the key issues for the UTC time transfer. This study is made in the framework of a joint task group of the CCTF Working Group on TWSTFT and Working Group on GNSS Time Transfer to investigate the long-term instability of
