✦ Synopsis

The relative concentrations of secreted proteins in liquid cultures of Neurospora crassa differ in constant darkness compared to constant light (2500 lx). Light reduces the concentrations of some polypeptides markedly and increases the concentrations of protein species of 67, 40, 18 and 13 kDa. The "blind" wc-2 mutant of Neurospora does not show light dependent differences in amounts of secreted proteins. One of the light-sensitive extracellular proteins is shown to be a protease of 17.5 kDa.
