Saccharomyces cerevisiae α‐factor prevents formation of glycoproteins in a cells

Abstract
α‐Factor inhibits incorporation of [14C]glucosamine into water‐soluble and into SDS‐extractable glycoproteins to about 90%. The incorporation into chitin is not affected and the same is true for [14C]phenylalanine incorporation into protein. The inhibition of glycoprotein synthesis is specific for a cells.
