Introduction.

Short-chain Dehydrogenase/Reductase (SDR) is a large protein family currently numbering about 2000 members (Kallberg et al. 2002). It also goes by the alternative name of the tyrosine-dependent oxidoreductase protein family (Edgar, 2002) because of their conserved tyrosine residue at position 152. Protein families are defined by their structural and functional similarities and generally have evolved from a common ancestor. SDR proteins have a length of about 250 amino acids (aa) and show approximately 15-30% sequence similarity/identity. This is relatively low when compared to other families. Despite this, members still have conserved structural folds and a conserved function.
