Protein

D-erythrulose reductase

Gene

DER

Organism
Gallus gallus (Chicken)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the reduction of D-erythrulose to D-threitol with the concomitant oxidation of NAD(P)H to NAD(P)+. NADH is less effective than NADPH. May also catalyze the reduction of L-xylulose.

Catalytic activityi

D-threitol + NADP+ = D-erythrulose + NADPH.
Xylitol + NADP+ = L-xylulose + NADPH.

    Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
    100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
    90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
    50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
