Does cycloheximide-induced loss of phosphate uptake activity in Neurospora crassa reflect rapid turnover?
Addition of cycloheximide to Neurospora crassa germlings growing in liquid medium caused an exponential loss of phosphate uptake activity (half-life, ca. 2 h). No loss of activity resulted when germlings were resuspended, at the time of cycloheximide addition, in medium of a substantially lower phosphate concentration. It is concluded that the phosphate uptake systems are not subject to rapid turnover.
