'''Mistletoe Lectin I from Viscum album in Complex with Adenine Monophosphate. Crystal Structure at 1.9 A Resolution'''

== Function ==
-
 
+
[https://www.uniprot.org/uniprot/ML1_VISAL 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.<ref>PMID:15182350</ref> <ref>PMID:15001393</ref> <ref>PMID:1450445</ref>

The crystal structure of the ribosome-inactivating protein (RIP) mistletoe lectin I (ML-I) from Viscum album in complex with adenine has been refined to 1.9 A resolution. High quality crystals of the ML-I complex were obtained by the method of vapour diffusion using the high density protein crystal growth system (HDPCG) on the international space station, mission ISS 6A. Hexagonal crystals were grown during three months under microgravity conditions. Diffraction data to 1.9A were collected applying synchrotron radiation and cryo- techniques. The structure was refined subsequently to analyse the structure of ML-I and particularly the active site conformation, complexed by adenine that mimics the RNA substrate binding.
