Trichodermin esterase activity and trichodermin resistance in Mucor racemosus.

W A Fonzi, P S Sypherd
PMCID: PMC180443  PMID: 3707105

Abstract

Mucor racemosus exhibited inducible phenotypic resistance toward the protein synthesis inhibitor trichodermin. Induction of resistance was elicited by exposure to trichodermin or to cycloheximide. Both adapted and nonadapted cells took up [14C]trichodermin from the medium. Trichodermin was found to be rapidly deacetylated to trichodermol upon entering the cell. Adapted cells deacetylated the drug more rapidly than nonadapted cells both in vivo and in vitro. The trichodermol resulting from deacetylation appeared in the medium, but the growth of adapting cells began well before the total conversion of trichodermin to trichodermol. Based on these data and the observation that trichodermol was a poor inhibitor of Mucor, adaptation appears to result from deacylation of the active antibiotic.
