the ftsz gene , coding for a cell division protein , was expressed at a higher level in the absence of camp , as measured with an ftsz : :lacz fusion , but the amount of protein per cell , shown by others to be invariable over a 10-fold range of cell mass , was independent of camp , suggesting that ftsz expression is not regulated by the camp-cap complex .
