Structure of glycerol dehydrogenase (GldA) from Escherichia coli

open access: yesActa Crystallographica Section F Structural Biology Communications, 2019
Escherichia coli (strain K-12, substrain MG1655) glycerol dehydrogenase (GldA) is required to catalyze the first step in fermentative glycerol metabolism. The protein was expressed and purified to homogeneity using a simple combination of heat-shock and chromatographic methods.

Hydrological excitation of polar motion by different variables from the GLDAS models [PDF]

open access: yesJournal of Geodesy, 2017
Continental hydrological loading by land water, snow and ice is a process that is important for the full understanding of the excitation of polar motion. In this study, we compute different estimations of hydrological excitation functions of polar motion (as hydrological angular momentum, HAM) using various variables from the Global Land Data ...
