Table 2 Substrate specificity

From: Characterization of the Kluyveromyces marxianus strain DMB1 YGL157w gene product as a broad specificity NADPH-dependent aldehyde reductase

Substrate Relative activity (%) a
Isovaleraldehyde 244 ± 1.9
Methylglyoxal 100
Valeraldehyde 95.6 ± 1.6
Hexanal 81.4 ± 1.4
Heptanal 80.8 ± 2.5
Furfural 60.1 ± 1.7
Propionaldehyde 49.3 ± 0.7
Octanal 22.3 ± 1.5
Benzaldehyde 14.3 ± 2.0
HMF 1.0
Cinnamaldehyde N/Ab
Vanillin N/Ab
  1. aReductive activities were measured in 100 mM acetate buffer (pH 5.5) containing 3 mM substrate, 0.1 mM NADPH and 100 nM enzyme.
  2. bN/A means no measurable activity. Due to the high absorbance of this substrate at 340 nm, activity was not determined under the assay conditions.
