Activating Compound

Activating Compound Comment Organism Structure
spermidine in presence of 50 mM K+, addition of spermine prevents inhibitory effect of 1.5 mM Mg2+ or above. In presence of 200 mM K+, the addition of spermine stimulates isoleucyl-tRNA formation in presence of Mg2+, 0-5 mM Rattus norvegicus

Inhibitors

Inhibitors Comment Organism Structure
Mg2+ in presence of 50 mM K+ and in absence of polyamines, the optimal Mg2+ concentration for Ile-tRNA formation is 1 mM, an increase in Mg2+ concentration markedly inhibits Rattus norvegicus
