Computational modeling of the molecular basis for the calcium-dependence of the mannuronan C-5 epimerase AvAlgE6 from Azotobacter vinelandii [PDF]

Computational and Structural Biotechnology Journal, 2023
The mannuronan C-5 epimerases catalyze epimerization of β-d-mannuronic acid to α-l-guluronic acid in alginate polymers. The seven extracellular Azotobacter vinelandii epimerases (AvAlgE1–7) are calcium-dependent, and calcium is essential for the ...

Protein flexibility drives sugar rotation and high substrate promiscuity in a GDP-sugar 4-epimerase [PDF]

Computational and Structural Biotechnology Journal
UDP-galactose 4-epimerases (Gal4Es) catalyze the inversion of the 4-hydroxyl configuration of a sugar moiety from an NDP-sugar through a three-step process: oxidation, rotation and reduction. Despite extensive biochemical and structural studies, the role
