Function
[ML1_VISAL] 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.[1] [2] [3]
About this Structure
3d7w is a 2 chain structure with sequence from Viscum album. This structure supersedes the now removed PDB entry 3cef. Full crystallographic information is available from OCA.
