Cat No.
NATE-0195
Description
D-lactic dehydrogenase catalyzes the conversion of D-lactate into D-pyruvate while reducing NAD+ to NADH and H+.
Abbr
D-LDH, Native (Lactobacillus leichmanii)
Alias
D-LDH
Species
Lactobacillus leichmanii
Form
Suspension in 3.2 M (NH4)2SO4, 0.1 M potassium phosphate, pH 7.0
Enzyme Commission Number
EC 1.1.1.28
Bio-activity
> 30 units/mg protein; ~1000 U/mL; 250-500 units/mg protein (biuret); 150-300 units/mg protein; 1,000-3,000 units/mg protein (biuret)
CAS No.
9028-36-8
Unit Definition
1 U corresponds to the amount of enzyme which will reduce 1 μmol of pyruvate to D-lactate per minute at pH 7.0 and 25°C
Applications
In the food industry, the primary catalysis is coupled to conversion of NADH and H+ to NAD+ with diaphorase coupled with converting the non-fluorescent resazurin to the highly fluorescent substance resorufin to measure the content of D-lactate in food products.
