ABSTRACT: Cloning, sequencing, and expression of the gene for soluble lysozyme of bacteriophage FMV from Gram-negative Pseudomonas aeruginosa bacteria were conducted in yeast cells. Comparable efficiency of two lysozyme expression variants (as intracellular or secreted proteins) was estimated in cells of Saccharomyces cerevisiae and Pichia pastoris. Under laboratory conditions, yeast S. cerevisiae proved to be more effective producer of phage lysozyme than P. pastoris, the yield of the enzyme in the secreted form being significantly higher than that produced in the intracellular form.
