In [[enzymology]], a '''2-hydroxy-3-oxopropionate reductase''' ({{EC number|1.1.1.60}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:(R)-glycerate + NAD(P)+ <math>\rightleftharpoons</math> 2-hydroxy-3-oxopropanoate + NAD(P)H + H<sup>+</sup>

The 3 [[substrate (biochemistry)|substrates]] of this enzyme are [[(R)-glycerate]], [[nicotinamide adenine dinucleotide|NAD<sup>+</sup>]], and [[nicotinamide adenine dinucleotide phosphate|NADP<sup>+</sup>]], whereas its 4 [[product (chemistry)|products]] are [[2-hydroxy-3-oxopropanoate]], [[nicotinamide adenine dinucleotide|NADH]], [[nicotinamide adenine dinucleotide phosphate|NADPH]], and [[hydrogen ion|H<sup>+</sup>]].

This enzyme belongs to the family of [[oxidoreductase]]s, specifically those acting on the CH-OH group of donor with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The systematic name of this enzyme class is '''(R)-glycerate:NAD(P)<sup>+</sup> oxidoreductase'''. This enzyme is also called '''tartronate semialdehyde reductase'''. This enzyme participates in [[glyoxylate and dicarboxylate metabolism]].

==Structural studies==

As of late 2007, only one [[tertiary structure|structure]] has been solved for this class of enzymes, with the [[Protein Data Bank|PDB]] accession code {{PDB link|1YB4}}.
