LITERATURE
the elevated specific activity of the palmitoleoyl transferase under conditions of cold shock is attributed to greatly increased levels of lpxP mRNA. Induced more than 30fold upon cold shock, as judged by assaying extracts of cells shifted to 12°C. The induced activity is maximal after 2 h of cold shock, and then gradually declines but does not disappear
the level of expression of lpxP is higher at 21°C than at 37°C
