一般說明
Research area: Cell Signaling
Lactic Dehydrogenase (LDH) is a cytoplasmic enzyme encoded by LDHA, LDHB, LDHC, and LDHD genes, and categorized as an oxidoreductase. It is widely distributed throughout the body, particularly in muscle, liver, and kidney. LDH demonstrates five isomeric forms that form tetramers with two types of subunits: muscle (M) and heart (H).

應用
L-Lactic Dehydrogenase from porcine heart has been used:
- as a component of the reaction buffer to measure the GTPase activity of EngA bound to the bacterial 50S subunit to study its structure and function.
- as a component of the enzyme solutions to test the sensitivity of multiphoton NAD(P)H fluorescence lifetime imaging (FLIM) in key enzymatic steps controlling the path of carbon from glucose uptake to electron transport chain (ETC) activity.
生化／生理作用
Also catalyzes the oxidation of other L-2-hydroxymonocarboxylic acids.
Lactate dehydrogenase (LDH) enzyme is responsible for the conversion of pyruvate to lactate, during glycolysis under hypoxic conditions, while also converting NADH to NAD+. Moreover it acts as a crucial regulator of gluconeogenesis and DNA metabolism. Increased serum LDH levels are detected in conditions such as cancer, HIV infection, muscular dystrophy, megaloblastic anemia, extreme hypothermia, hepatitis, meningitis, hypoxia, etc.
單位定義
One unit will reduce 1.0 μmole of pyruvate to L-lactate per min at pH 7.5 at 37 °C.
