| Research Abstract |
Some Bacillus subtilis natto phages carry gamma-poly glutamate hydrolase gene on their genome, and this gene is strongly expressed during phage lytic cycle. To apply this system for the foreign gene expression system, we determined complete genome sequence of phage phiNIT1 and analyzed the expression system of gamma-PGA hydrolase gene.
As a result, we found that not only phage encoded elements but also both of cis-elements and trans-elements in the bacterium were required for the gene expression. In addition, we identified phage proteins involving in specific recognition of host cell surface.
