Native Lactobacillus delbrückii D-Lactate Dehydrogenase, Grade II

Cat No.
NATE-0977
Description
In enzymology, a D-lactate dehydrogenase is an enzyme that catalyzes the chemical reaction: (D)-lactate + 2 ferricytochrome c↔ pyruvate + 2 ferrocytochrome c. Thus, the two substrates of this enzyme are (D)-lactate and ferricytochrome c, whereas its two products are pyruvate and ferrocytochrome c. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with a cytochrome as acceptor. This enzyme participates in pyruvate metabolism. It employs one cofactor, FAD.
Abbr
D-LDH, Native (Lactobacillus delbrückii)
Alias
D-LDH
Source
Lactobacillus delbrückii
Applications
Use D-Lactate Dehydrogenase (D-LDH), Grade II, in a variety of diagnostic tests, e.g., in the determination of alanine aminotransferases, lactate or pyruvate. Used for the removal of pyruvate in determinations working with NADH (i.e., triglycerides, lipase, aldolase, aspartate aminotransferases, glutamate dehydrogenase).
Appearance
White to yellowish lyophilizate
