Data extracted from this reference:
Application
2.7.1.145
synthesis
the cross-linked DmdNK preparation is used for the preparative synthesis of arabinosyladenine monophosphate (ara-AMP) and fludarabine monophosphate (FaraAMP)
Drosophila melanogaster
Engineering
2.7.1.145
additional information
enzyme DmdNK is adsorbed on a solid ion exchange support (bearing primary amino groups) achieving an expressed activity of over 98%. Upon cross-linking with aldehyde dextran, the expressed activity is 30-40%, both biocatalysts (adsorbed or cross-linked) are stable at pH 10.0 and room temperature for 24 h with about 70% of retained activity. Optimization of the reaction conditions to 50 mM ammonium acetate, a substrate/ATP ratio of 1:1.25, 2 mM MgCl2, 37°C, pH 8.0, results in conversions of up to 90%
