Abstract


Nikkomycin Z (NZ) is a competitive inhibitor of chitin synthase III in the yeast Saccharomyces cerevisiae. Myosin type II-deficient yeast strains (myo1) display a dramatic reduction in growth when chitin synthase III activity is inhibited by NZ, supporting the contention that actomyosin motility plays an important role in maintaining cell wall integrity. A proposed inhibitor of cortical actin polymerization in vitro, 2,3-butanedione monoxime (BDM), also inhibits growth of wild-type yeast strains at a concentration of 20 mM. In this study, we assayed for potential in vivo interplay between BDM-sensitive cell functions and cell wall chitin synthesis by testing for increased sensitivity to NZ during co-treatment with BDM at sub-inhibitory concentrations. Our results show that BDM can increase the sensitivity of yeast cells to Nikkomycin Z.
