The addition of Ca2+-antagonizers (La2+), Ca2+-ionophores (A23187) and Ca2+-complexing agents (EGTA) inhibited the formation of xylanase activity in resting mycelia of Trichoderma reesei. The inhibition by the ionophore was reversed by the addition of Ca2+ ions. A similar inhibitory effect was obtained by the addition of the calmodulin inhibitors, trifluoroperazine, chlorpromazine and quinacrine, hence suggesting that the observed effect of Ca2+ on xylanase formation occurred via calmodulin… CONTINUE READING
