Figure 4
Mean value of the χ1 gauche− rotamer as a function of resolution and secondary structure for leucine (independent of χ2). (a) Values reconstructed from the study of MacArthur & Thornton (1999). (b) As in (a) but for a much larger data set (see §2) and subdivided for secondary structure. Colour coding is the same as in Fig. 2. Each dot represents at least 50 observations. Error bars represent the standard errors of the mean. |
