摘要:
An improved hydroxynitrile lyase characterized by having a mutation of substitution of at least one amino acid residue in the amino acid sequence of a wild-type hydroxynitrile lyase with another amino acid and by its hydroxynitrile lyase activity per transformant being higher than the hydroxynitrile lyase activity per transformant into which the wild-type hydroxynitrile lyase gene is introduced; and a method for producing a hydroxynitrile lyase, comprising expressing the improved hydroxynitrile lyase in a host and recovering the improved hydroxynitrile lyase from the resultant culture.

The present invention provides an industrially useful improved halohydrin epoxidase, a method for producing the same, and a method for producing an epihalohydrin or 4-halo-3-hydroxybutyronitrile using the same. The improved halohydrin epoxidase of the present invention consists of an amino acid sequence in which a specific amino acid substitution mutation is introduced into an amino acid sequence of a wild-type halohydrin epoxidase comprising predetermined amino acid sequences I and II.

This invention provides a process for producing a vinylated nucleic acid in an efficient and cost-effective manner through the implementation of vinylation of an amino-containing nucleic acid with a vinylating agent. This invention also provides a process for producing a vinylated nucleic acid in an efficient and cost-effective manner by a method in which PCR is carried out in the presence of an amino-modified nucleotide and dNTP and a vinyl group is introduced into the resulting PCR amplification product or by a method in which PCR is carried out in the presence of a vinyl-modified nucleotide and cNTP.

摘要:
The invention relates to a DNA coding for a polypeptide having nitrilase activity with an amino acid sequence as shown in SEQ ID NO:1. As compared with conventional processes, the hydrolysis of nitriles by a nitrilase gene cloned by genetic recombination is expected to drastically improve the catalytic ability of microorganisms because they can be engineered to contain multiple copies of the same gene.
