The data indicate that a substantial induced-fit conformational change accompanies P1 formation, and they provide a physical basis for understanding the transport of oligonucleotides to the catalytic core of the ribozyme.
Inflammation and growth pathways have substantial overlap, fitting with the idea that postdevelopmental growth is in large part modulated by environmental stimuli such as exercise.
Given the heterogeneity (I = 46.9%), a random-effects model fitted the data well while the fixed-effect model showed substantial lack of fit.
Other notable features include a substantial rearrangement (induced fit) of aromatic side-chains in ZTaq upon binding, a close contact between glycine residues in the two subunits that might involve aliphatic glycine Hα to backbone carbonyl hydrogen bonds, and four hydrogen bonds made by the two guanidinium NηH2 groups of an arginine side-chain.
Evidence ratios (wm/wm') greater than 2.718 indicated a substantial improvement in fit of model m over model m', being equivalent to a difference in AIC (Δm) of greater than two [21].
The size of the chi-square can be seen as reflecting the large sample size rather than a substantial lack of fit.
Further, the substantial improvement in fit residual on addition of the metal metal vector suggests that metal binding is cooperative, with the dominant species present at substoichiometric metal loading being the apo- and dizinc enzymes.
We dropped 31 out of 219 items, either because of lack of fit, substantial DIF in relation to sex or age, or because of an extremely skewed distribution (one item).
A broader examination of the properties of a series of fully parameterized models both for independent and overlapping-tuple cases has also been done [ 16], demonstrating a substantial improvement in fit conferred by context dependent models over independent nucleotide models.
Model modification indices suggested that substantial improvement in fit could be obtained by including covariances among the residual errors of the SF-36 domains for RP and GH, VT and SF, and RP and RE.
