FIELD: biotechnology.
SUBSTANCE: method of highly effective production of methionine-containing form of staphylokinase (SAK-1) and some of its biologically active analogs in a host cell, providing culturing a bacterial cell transformed by the expression vector which comprises the DNA sequence encoding SAK-1 at a high degree of aeration and reducing the level of oxygen by 5% of atmospheric level with achievement the exponential growth phase.
EFFECT: use of the invention provides a significant increase in the yield of the target product.
