This closed conformation with apparent higher affinity to the cofactor is also observed in the unliganded crystal form, indicating that the NADP(H) binding to TtAroE may follow the selection mode where the cofactor binds to the subunit that happens to be in the closed conformation in solution.
In general, six parameters must be set to conduct a GA search: (1) the population size (N), (2) the selection mode, genetic operators through (3) crossover and (4) mutation types, as well as their respective activation probabilities, (5) p(_{c}) and (6) p(_{m}).
Here, we adopted phylogenetic comparison of synonymous and nonsynonymous substitution rates to tell the selection mode between PvC3H paralogous genes (Table 1).
Non-synonymous (Ka) to synonymous (Ks) substitution rates were used to estimate the selection mode for all orthologous gene pairs of soybean SWEET family [ 48].
The above two selection modes commonly indicate that the 3′ portion or the 3′ end of the miRNA sequence contains a critical sorting signal.
At a generation, each locus was characterized by the selection coefficient s and (for the switching selection mode) the waiting time for this coefficient to switch sign.
As a result, the significance of the occurrence of the positive selection mode for a cluster of a particular functional class was established (PS = 1).
On the other hand, f ij is added to both seed feature sets M i and M j for the other two selection modes (line A2 7 9).
In feature selection, "cross-validation" was selected as the attribute selection mode, and tenfold splits as default were performed.
The optimization procedure was repeated 100 times, and final conservation scenarios were obtained after 20 million iterations, implemented in the Site Selection Mode routine of the software SITES [47], [48].
For each anuran subset (i.e. species with aquatic larvae or terrestrial development), we ran a simulated annealing procedure in the Site Selection Mode (SSM) routine of the SITES software program [53] [54] to find these combinations of ecoregions.
