Abstract: Incubation of Mucor rouxii sporangiospores in complex medium under aerobic conditions resulted in a transient 20-fold increase in trehalase activity. Maximum activity was reached after 15 min. Simultaneously, the cyclic AMP (cAMP) content increased approximately eightfold, reaching a maximum within 10 min. Increases in trehalase activity and cAMP content were also observed under anaerobic conditions (CO2). The extent of trehalase activation and the changes in cAMP content, during both aerobic and anaerobic incubation, varied with the medium used. Trehalase was activated in vitro by a cAMP- and ATP-dependent process. An even faster activation was obtained when cAMP was replaced by the catalytic subunit of beef heart protein kinase. The coincidence of, and the correlation between, increased cAMP contents and trehalase activities support the involvement of a cAMP-dependent phosphorylation in the in vivo regulation of trehalase activity.
