38aa with T1 terminator and Constitutive promoter veg

Human lysozyme (hLZ), the actual protein in breast milk,exhibits microbicidal activity to various degrees against several bacterial strains.The HLH peptide and its N-terminal helix (H1) were significantly the most potent bactericidal to Gram-positive and Gram-negative bacteria.Evidence shows that HLH peptide and its N-terminal helix (H1) kill bacteria by crossing the outer membrane of Gram-negative bacteria via self-promoted uptake and are able to dissipate the membrane potential-dependent respiration of Gram-positive bacteria.

Experiment

In order to distinguish whether the B. Subtilisexpress our objective protein or not,we used the method of in-vitro bacterial inhibition zone to observe the anti-bacterial effect.We added 100 ul B. Subtilis liquid medium into the hole. The inhibition zone results showed that gram-positive bacterium was sensitive to 38aa.
