• UniProt ID: P23368
• MW: Approximately 64.4 kDa, a single non-glycosylated polypeptide chain containing 573 amino acids with 6 x His at C-terminus.
• Expression System: Escherichia coli
• Endotoxins: Less than 1 EU/ugof rHuME2, His as determined by LAL method.
• Source: Escherichia coli
• Biological Activity: Malic Enzyme activity was assayed spectrophotometrically at 340nm as described in Mandela and Sauer (1975). The standard reaction mixture contained 50 mM Tris-HCl, 3 mM MnCl2, 5 mM malate, 0.12 mM NADP+, 2.5 mM fumarate. Assay was performed in a Beckman spectrophotometer. The Km value is 1.5 �� 0.6 mM.
• Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
• Alternative names: NAD-dependent Malic Enzyme, Mitochondrial, NAD-ME
