Inhibitor of Transfer Ribonucleic Acid Methylases in the Differentiating Slime Mold Dictyostelium discoideum

AUTOR(ES)
RESUMO

Eight hours after the onset of morphogenesis, an inhibitor of transfer ribonucleic acid methylases appears in differentiating Dictyostelium discoideum. The inhibitor is also present in spores. Fifty per cent of the inhibiting activity is lost upon heating at 100 C for 5 min; it is nondialyzable and sensitive to trypsin.
