<p>This entry represents an NAD/NADP-binding domain with a core Rossmann-type fold, found in an uncharacterised protein family thought to be putative NADP oxidoreductase coenzyme F420-dependent proteins and/or NAD-dependent glycerol-3-phosphate dehydrogenase-like proteins. This Rossmann-fold domain consists of 3-layers alpha/beta/alpha, where the six beta strands are parallel in the order 321456.</p>
