Outline of Final Research Achievements

In Selenomonas ruminantium, cadaverine serves as an essential constituent of the peptidoglycan for the maintenance of envelope integrity through the interaction with SLH domain of Mep45, the outer membrane protein. Cytoplasmic biosynthesis of cadaverine occurs totally in a eukaryotic-like manner. Lysine/ornithine decarboxylase (LDC/ODC), responsible for cadaverine synthesis in this bacterium, displays significant homology to the eukaryotic ODC, and its activity is tightly regulated by antizyme(L10)-mediated proteolysis. Here, we show the following 4 findings, i.e. (i) Determination of the complete genome sequence of S. ruminantium, (ii) Molecular mechanism of Mep45 function. We found that Mep45 forms a non-specific diffusion channel in its C-terminal region, (iii)Identification of the ATP-dependent ClpX/P for degradation of LDC/ODC, which is mediated by L-10 and (iv) Identification of an enzyme for cadaverine-adding reaction into the peptidoglycan of this bacterium.
