A staphylococci kinase and a method for high efficiency secreting and expressing recombination staphylococci kinase in biotechnology are provided. It obtains glucose kinase (Sak) containing signal peptide by using total DNA of staphylococcus aureus as form through PCR amplification. The 33th, 34th and 36th bite amino acid of the gene order are different from the reported Sak gene. Connecting the gene to carrier Pgex-4T-1, then transforming host bacterium to obtain recombination engineering bacterium. The recombination engineering bacterium can secreted express recombination glucose kinase having the function of fiber dissolvedzymogen activation by IPTG induction. The recombination glucose kinase expressed in the method of the invention has high gene expression and expressed outcome mainly is secretion type albumen which exists in thalli outer cytoplasm or outer cell. Thus, purifying process is simple, yield is high and production cost is low.
