Figure 5

Distribution of maxGLN, minGLN and whGLN values based on the 13,320 loops closed by disulfide bridges. Panels (A–C) indicate that there are more negative GLN values than positive ones in proteins. (A) Histogram of all maxGLN and minGLN values that are greater than 0.15 or lower than \(-\,0.15\), and 53% of them are negative. (B) Histogram of all maxGLN or minGLN values (only greater value—in the sense of absolute value—from each pair is taken into account here) from the loops of gL\(_1\) type—over 63% of them are negative. (C) Histogram of all whGLN values in the analyzed dataset revealing the local minimum around the value \(-\,0.5\). (D) Histogram of whGLN for random polymers.
