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

Overview

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.
