ML1_VISAL Beta-galactoside-specific lectin I ML-I B Beta-galactoside-specific lectin I chain B Beta-galactoside-specific lectin 1 chain B 564 Viscumin The A chain is responsible for inhibiting protein synthesis through the catalytic inactivation of 60S ribosomal subunits by removing adenine from position 4,324 of 28S rRNA. The B chain binds to cell receptors and probably facilitates the entry into the cell of the A chain; B chains are also responsible for cell agglutination (lectin activity). Inhibits growth of the human tumor cell line Molt4.
