EC 220.127.116.11, SORD1, SORD, L-iditol 2-dehydrogenase, DHSO, Sorbitol Dehydrogenase,
SDH, (R,R)-butanediol dehydrogenase, L-iditol 2-dehydrogenase, Polyol dehydrogenase, Ribitol dehydrogenase, RDH, Xylitol dehydrogenase, XDH
SORD, also referred to as sorbitol dehydrogenase, belongs to the zinc-containing alcohol dehydrogenase family. It is widely produced. The lens of the eyeand the kidney are the protein highest production areas. Zinc-dependent interconversion of polyols, like sorbitol and xylitol, are enzymatically catalysed to their respective ketoses by SORD.
SORD Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 357 amino acids (1-357a.a.) and having a molecular mass of 38.3kDa.
SORD is purified by proprietary chromatographic techniques.
The SORD solution (0.5mg/ml) contains 10% glycerol, 20mM Tris-HCl buffer (pH 8.5) and 1mM DTT.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
Specific activity > 15unit/mg. Defined by the amount of enzyme that catalyze the reduction 1.0 umole of D-fructose to D-sorbitol per minute at pH 7.5 at 37˚C.
