abstract：:Downstream from the ptsHI operon of Lactobacillus sakei, the genes atkY and atkB, organized in an operon, were observed. The two putative proteins, AtkB and AtkY, show sequence similarity to the Enterococcus hirae copper P-type ATPase, responsible for copper efflux, and its negative regulator. Characterization of AtkB...
