Descripción general
Glycerol Dehydrogenase belongs to iron-containing alcohol dehydrogenase family. It is made up of eight identical subunits which are about 42,000 Da each. The C-terminal has histidine and the N-terminal has serine amino acid.
Aplicación
Glycerol Dehydrogenase (GDH) from Cellulomonas sp. has been used in the determination of glycerol by sequential injection analysis (SIA) method. It has also been used in the preparation of pyrroloquinoline quinone (PQQ) based biosensor for the determination of glycerol.
This enzyme is useful for enzymatic determination of glycerol and of triglyceride when coupled with lipoprotein lipase in clinical analysis. Formation of NADH from the reaction of glycerol and NAD+ was catalyzed by the enzyme glycerol dehydrogenase.
Acciones bioquímicas o fisiológicas
Glycerol dehydrogenase catalyzes the conversion of glycerol to glycerone.
