Synthesis of beta-glucanase and other extracellular proteins by cells and protoplasts of the yeast Pichia polymorpha: effect of 2-deoxy-D-glucose.

The synthesis of beta-glucanase either by cells or by protoplasts of the yeast Pichia polymorpha has been found to occur in the presence of 2-deoxy-D-glucose in the growth medium. On the other hand, the synthesis of typical extracellular proteins such as invertase and acid phosphatase is strongly affected by the presence of the drug. The degree of inhibition is, however, directly related to the 2-deoxy-D-glucose concentration.
