Abstract
Bacteria, like eukaryotic cells, regulate their size by coordinating cell growth and division, growing faster and becoming larger when nutrients are more plentiful. Weart et al. (2007) now identify an enzyme in a glucolipid pathway that inhibits assembly of the key cell division protein FtsZ, but only during high nutrient conditions. Delaying cell division during rapid growth allows bacterial cells to become larger.
