The nitrilase superfamily is a large and diverse superfamily of enzymes that catalyse the cleavage of various types of carbon-nitrogen bonds using a Cys-Glu-Lys catalytic triad. Thermoactive nitrilase from Pyrococcus abyssi (PaNit) hydrolyses small aliphatic nitriles like fumaro- and malononitryl.

A new versatile acrylonitrile-bioconverting strain isolated from a petroleum-contaminated sludge sample and identified as Rhodococcus ruber AKSH-84 was used for optimization of medium and biotransformation conditions for nitrilase activity to produce acrylic acid. A simple and rapid HPLC protocol was

Nitrilases are oligomeric, helix-forming enzymes from plants, fungi and bacteria that are involved in the metabolism of various natural and artificial nitriles. These biotechnologically important enzymes are often specific for certain substrates, but directed attempts at modifying their substrate specificities

Several environmental samples from Antarctica were collected and enriched to search for microorganisms with nitrilase activity. A new thermostable nitrilase from a novel hyperthermophilic archaea Pyrococcus sp. M24D13 was purified and characterized. The activity of this enzyme increased as the

Nitrilases from Aspergillus niger CBS 513.88, A. niger K10, Gibberella moniliformis, Neurospora crassa OR74A, and Penicillium marneffei ATCC 18224 were expressed in Escherichia coli BL21-Gold (DE3) after IPTG induction. N. crassa nitrilase exhibited the highest yield of 69,000 U L(-1)

Questions

1–3 of 3 Questions  
  1. what is the bacteria or organism whose genome sequence have been expressed in E.Coli for nitrilase procurement? I need the name of the organism for research purpose

    1 answer
    1. This enzyme is a recombinant protein produced in e. coli. The biological source and sequence of the protein is considered proprietary and may not be shared.

      Helpful?

  2. Can we get the source of the bacteria or organism whose genome sequence is being used for recombinant expressing in E.Coli for procuring nitrilase. Used for research purspose by a student

    1 answer
    1. Unfortunately, the source and sequence is considered proprietary.

      Helpful?

  3. Is the nitrilase been synthesized through DNA recombinant technology or is there any other source organism from which the nitrilase has been procured?

    1 answer
    1. Yes, this product is a recombinant protein expressed in E. coli.
