Native Lactobacillus leichmanii D-Lactic Dehydrogenase

inquiry

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

Source

Lactobacillus leichmanii

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.

Form

Suspension in 3.2 M (NH4)2SO4, 0.1 M potassium phosphate, pH 7.0

Enzyme Commission Number

EC 1.1.1.28

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

Storage

2-8°C

Synonyms

EC 1.1.1.28, D-Lactic Dehydrogenase; 9028-36-8; lactic acid dehydrogenase; D-specific lactic dehydrogenase; D-(–)-lactate dehydrogenase (NAD); D-lactic acid dehydrogenase; D-lactic dehydrogenase; (R)-Lactate:NAD+ oxidoreductase; D−LDH
