Results/structure

Dehydrogenase/reductase SDR family member 1 has highly conserved structure compared across the SDR family.

SDR family is part of the Super Family; NAD(P)-binding Rossmann-fold domain proteins all of which have the Rossmann-fold domain, which is characterised a central β-sheet surrounded by α-helicies. This puts them in the Alpha and Beta proteins (α/β) class.

Some key residues are conserved across the entire family. Notable a Tyrosine that binds NADPH. It is part of a larger motif (SxxxxxxxxxxxxYxxxK) that includes two other residues involved in binding NADPH.

There is another highly conserved motif (LDVLD) involved in the initial folding of the protein. It forms part of the hydrophobic core most notably a strand of the β-sheet that is part of the Rossmann-fold.
