FIELD: biotechnology.
SUBSTANCE: proposed enzymatically inactive IgA1 protease with replacement Ser267Ala for use as a component of a polyvalent vaccine designed to protect people against meningococcal infection and other microorganisms, which pathogenicity is caused by IgA1 protease. The invention includes a polynucleotide encoding the said mutant form of IgA1 protease of Neisseria meningitidis of serogroup B, comprising the said polynucleotide, a recombinant plasmid DNA, the strain Escherichia coli - producer of a mutant form of IgA1 protease according to the invention, the method of preparing a recombinant form of the enzyme using a technology of recombinant DNA, and recombinant inactivated IgA1 protease.
EFFECT: increased level of immunogenicity.
