In general, polar amino acids are statistically disfavoured in interfaces sites, with the exception of arginine [ 18, 35].
EcoCas1 displayed a striking preference for a guanine at the +1 position for the disintegration reaction, with all three alternative nucleotides strongly disfavoured at this position, in good agreement with the prediction based on the repeat sequence.
Thus, 1,2-insertion is clearly disfavoured kinetically over 2,1-insertion, consistent with the observation of only 1,2-disubstituted alkenes experimentally.
This suggests that the two pathways dimer-to-soluble aggregate and from the soluble-to-insoluble aggregate have a similar efficiency only for GST, whereas one of them is disfavoured in GST-Q22 and GST-Q41 with consequent, if transient, formation of a reservoir of soluble high molecular weight intermediates or protofibrils.
On the other hand, histone methylations associated with heterochromatin regions, like H3K9me3, were disfavoured by the MLV vector equally in both cell types.
These patterns are, to an extent, reminiscent of those observed in the X=O analogues, with a para-chloro substituent being highly disfavoured (7 e, 710 μ m; 7 h, inactive), and an ortho-ethyl group supporting inhibitory activity of these compounds (1 b, 24 μ m; 7 i, 75 μ m).
Indeed, they fell into disfavour with the Hasmonean rulers.
Throughout pharaonic history the oases served as places of exile or refuge for those in disfavour with the government.
One of them, Postumus, reportedly no more than a boor, fell into disfavour with Augustus and was sent into exile with his mother.
