title: Interaction between glyceraldehyde-3-phosphate-dehydrogenase and lactate dehydrogenase.
abstract: Physical interaction between rabbit muscle glyceraldehyde-3-phosphate dehydrogenase and lactate dehydrogenase was detected by means of matrix immobilization technique. Glyceraldehyde-3-phosphate dehydrogenase covalently bound to CNBr-activated Sepharose 4B was capable of forming a complex with soluble lactate dehydrogenase with a stoichiometry of 0.8 mole of lactate dehydrogenase per mole of glyceraldehyde-3-phosphate dehydrogenase and KD of 0.385 microM at pH 6.5. The bienzyme association weakened when pH changed to 7.0 (the KD increased to 1.25 microM).
