Each data point represents a rate of protein synthesis determined from the slope of a separate time-course experiment, based on multiple samples (as in Fig. 2). The decrease in protein synthesis with development was fitted to a second-order polynomial: ng protein synthesized larva"1 day"' = — .v + , where v = age in days. glycine in the proteins of 2- to 8-day-old larvae was (± SEM), and this value was used for all calculations of protein synthesis rates. The mole-percent corrected molec- ular weight of amino acids in larval protein ranged from to g amino acid mol~', with a mean value of (± SEM) used for all calculations (Table I). Rates of protein synthesis Rates of protein synthesis decreased during development, from 193 to 49 ng protein synthesized larva" ' day"1 (cal- culated from analysis given in Table II of data shown in Fig. 5). The decrease was nonlinear and was best described by a second-order polynomial (nanograms of protein synthesized per larva = x2 — .v + where ,v = age in days). The fractional rate of protein synthesis, expressed as the percentage of total whole-body protein synthesized per day. also showed a steady decline through larval develop- ment and decreased from 40% (1-day-old) to 14% (7-day- old) (Table II: comparison of total protein content per larva and absolute rate of protein synthesis).
