일반 설명

Nitrilase belongs to the C-N hydrolase superfamily.[1] It possesses the catalytic triad motifs: glutamate, lysine, and cysteine and are distributed in fungi, plants, and animals.[2]The isoelectric point (pI) of this protein is 8.1. Native polyacrylamide gel electrophoresis (PAGE).

애플리케이션

Nitrilase may be used for immobilization on acryloyl crosslinked cellulose dialdehyde (ACCD) for catalytic activity studies.[3]

생화학적/생리학적 작용

Nitrilases catalyze the liberation of ammonia and the formation of carboxylic acid from the nitriles.[4] The oligomeric structural organization of nitrilase is crucial for its functionality.[1] It displays broad substrate specificity.[1]

포장

Bottomless glass bottle. Contents are inside inserted fused cone.

단위 정의

1 U corresponds to the amount of enzyme which liberates 1 μmol ammonia per minute at pH 7.2 and 25°C with the conversion of acrylonitrile to acrylic acid

Formamidases (EC 3.5.1.49) are poorly characterized proteins. In spite of this scarce knowledge, ammonia has been described as playing a central role in the pathogenesis of human pathogens such as Helicobacter pylori, for which formamidase has been shown to participate

In this study, several nitrilase genes from phylogenetically distinct organisms were expressed and purified in E. coli in order to study their ability to mediate the biotransformation of nitriles. We identified three nitrilases: Acidovorax facilis nitrilase (AcN); Alcaligenes fecalis nitrilase

Microbial nitrilases are biocatalysts of interest and the enzyme produced using various inducers exhibits altered substrate specificity, which is of great interest in bioprocess development. The aim of the present study is to investigate the nitrilase-producing Alcaligenes faecalis MTCC 10757

The characteristics of the new nitrilase-producing strain Rhodobacter sphaeroides LHS-305 were investigated. By investigating several parameters influencing nitrilase production, the specific cell activity was ultimately increased from 24.5 to 75.0 μmol g(-1) min(-1), and hereinto, the choice of inducer proved

The enantioselective hydrolysis of mandelonitrile with whole cells of a recombinant Escherichia coli expressing nitrilase activity was severely inhibited by the substrate at high concentrations (>300mM), which resulted in a low yield of the target product (R)-(-)-mandelic acid. To relieve
