(2011) Nat Struct Mol Biol Modeled by MOE showing an effective interaction of the SLAM N-terminal region. MD simulations confirmed stability of the complex. RMSF was calculated for all residues of hSLAM, and FMO computation analysis revealed a CH-pπ interaction between Met29 (hSLAM) and Phe549 (MV-H).
