General description
Octopine dehydrogenase (OcDH) is from the adductor muscle of a scallop and it catalyses the NADH-dependent condensation of l-arginine and pyruvate to d-octopine, NAD(+) and water during escape swimming and subsequent recovery.
Application
Octopine dehydrogenase has been used in a study to assess metabolic and physiological responses in tissues of the long-lived bivalve Arctica islandica to oxygen deficiency. It has also been used in a study to investigate biochemical responses of the marine mussel Mytilus galloprovincialis to petrochemical environmental contamination.
Biochem/physiol Actions
Octopine Dehydrogenase activity can be inhibited by treatment with the dialdehyde, o-phthalaldehyde.
Unit Definition
One unit will form 1.0 μmole of octopine from 1.0 μmole of pyruvate and 1.0 μmole of L-arginine per min. at pH 6.6 at 25 °C.

Contains Tris buffer salts
