일반 설명

L-Glutamate Oxidase (LGOX) from Streptomyces sp is secreted extracellularly in the wheat bran pre cultivation medium. It corresponds to a molecular weight of 120 kDa with monomer subunit of 61 kDa. The structure of LGOX comprises of hexamer and has flavin adenine dinucleotide prosthetic group.
This product has a 6xHistidine tag with a thrombin cleavage site.

애플리케이션

L-Glutamate Oxidase from Streptomyces sp may be used:
  • as a reference enzyme in hydrogelpoly(carbamoylsulphonate) based immobilization for biosensor development
  • as a component of pencil graphite electrode for biosensing L-glutamate

생화학적/생리학적 작용

L-Glutamate Oxidase (LGOX) catalyzes the oxidative deamination of L-glutamate to α-ketoglutarate, ammonia and hydrogen peroxide. LGOX is industrially produced and is exploited majorly as a biosensor for L-glutamate detection and in the L-glutamate kits.

단위 정의

One unit will form 1.0 micromole of alpha-ketoglutaric acid from L-glutamic acid per minute at pH 7.4 at 30 deg C.
