Glyceryl-Ether Monooxygenase [EC 1.14.16.5J Part VIII. Probing the Nature of the Active Site

open access: yesPteridines, 1995
The V /K kinetic parameters for glyceryl-ether monooxygenase with 3-1 '-n-alkoxypropane-I,2-diols having alkyl sidechains varying from Cll to C22 (lb-k, 2a and b, and 3d) were determined. Maximum activity was found with the CI6 ethers, dropping almost to

An investigation of the formation and line properties of MgH in 3D hydrodynamical model stellar atmospheres [PDF]

open access: yes, 2017
Studies of the isotopic composition of magnesium in cool stars have so far relied upon the use of one-dimensional (1D) model atmospheres. Since the isotopic ratios derived are based on asymmetries of optical MgH lines, it is important to test the impact ...
