Abstract
Under restricted culture conditions, the growth and division of Saccharomyces cerevisiae was inhibited by the antimitotic drug Colcemid; in contrast, the related drug colchicine had no effect. The difference in the sensitivity of yeast to these two agents was not dependent on their ability to permeate the cell but rather reflected an inherent difference in the affinity of the two drugs for a cellular-binding site. The binding moiety was characterized by gel filtration as a macromolecule of approximately 110,000 mol wt with an affinity constant for Colcemid of 0.5 x 104 liters per mole; in addition, this macromolecule was retained by diethylaminoethyl (DEAE) ion exchangers. On the basis of these properties, the Colcemid-binding substance in S. cerevisiae cells was provisionally identified as microtubule subunits.
