{"target":"http://pubannotation.org/docs/sourcedb/PMC/sourceid/2728246","sourcedb":"PMC","sourceid":"2728246","source_url":"https://www.ncbi.nlm.nih.gov/pmc/2728246","text":"For four leucines, L8, L50, L67, and L73, RDC-based order parameters were available both for Cδ1 and Cδ2. For L8, L50, and L67, (Cδ1) and (Cδ2) were identical within the error. The same also holds for the amplitudes of anisotropy. This indicates isotropic behavior for the leucines apart from L73 in the very flexible C-terminal part of ubiquitin. L73, being very mobile, shows a statistically significant difference both in order parameter and amplitude of anisotropy with (Cδ1) = 0.05 ± 0.04 and (Cδ2) = 0.18 ± 0.06 and η(Cδ1) = 0.83 ± 0.15 and η(Cδ2) = 0.14 ± 0.11. The difference in η looks very dramatic, however, it must be realized that in this case, big differences in η can occur even if the motion of the two methyl groups is not vastly different, given the very low order parameter.","tracks":[]}
