A closer or further location of the aromatic rings to the peptide backbone in the mutants relative to F13 is proposed to cause a drop in activity.
Previously it has been experimentally shown that the exchange of a series of rare codons by frequent synonymous codons downstream of the third RCRR and overlapping with the fourth RCRR (S124DTKLFPQGVTPENHLNISAL144) supposedly led to the elimination of a translational pause in this region and caused a drop in specific activity by 20% [ 8].
In exchange, the Iranians wanted guarantees that if they took such steps, the West would ease tough sanctions on oil exports, banks and other economic activities that have caused a drop in oil production from 4.2 million to 2.6 million barrels per day and a decline of nearly 80 percent in the value of the Iranian rial.
Tuition failed to cover rising costs, and in turn, tuition increases caused a drop in enrollment.
In the fly, tissue-restricted dFOXO triggers endocrine factors to cause a drop in overall, systemic, IIS activity (Bai et al., 2012, Bai et al., 2013, Demontis and Perrimon, 2010, Hwangbo et al., 2004).
Researchers have warned that although formulary access restrictions are designed to reduce costs, '… if they cause a drop in patient persistence, or a flurry of activity (switching) with each new list that is adopted, there could be negative consequences for both patients and the Medicaid budget'[ 110].
The shortage of organic acid as it gradually decreased in the substrate constrained methanogen activity, but stimulated acidogene, causing a drop in methane yield.
