Glycerol dehydrogenase

Gene

gldA

Organism
Geobacillus stearothermophilus (Bacillus stearothermophilus)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the NAD-dependent oxidation of glycerol to dihydroxyacetone (glycerone). Allows microorganisms to utilize glycerol as a source of carbon under anaerobic conditions. Is also able to use various diols as substrates, such as propan-1,2-diol, butan-2,3-diol, ethan-1,2-diol, and 3-mercapto-1,2-dihydroxypropane.1 Publication

Catalytic activityi

Glycerol + NAD+ = glycerone + NADH.

    pH dependencei

    Optimum pH is 6.0-8.5.1 Publication

    Pathwayi: glycerol fermentation

    This protein is involved in step 1 of the subpathway that synthesizes glycerone phosphate from glycerol (oxidative route).
    Proteins known to be involved in the 2 steps of the subpathway in this organism are:
    1. Glycerol dehydrogenase (gldA)
    2. no protein annotated in this organism
    This subpathway is part of the pathway glycerol fermentation, which is itself part of Polyol metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes glycerone phosphate from glycerol (oxidative route), the pathway glycerol fermentation and in Polyol metabolism.

    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.
