Nevertheless, phylogenetic analysis would have enabled identification of viable substitutions for several Phe positions targeted in the different GFP constructs made, indicating its utility in combination with random approaches.
In addition to a cascade-initiating 1,5-diene, 1,6-dienylphenol 7 was also shown to be a viable alkene substitution pattern and was computationally investigated in collaboration with the Morokuma group (Scheme 4).
The single P49A substitution is viable, and shows no reduction (even an increase) of H2A.Z levels on a sample of yeast gene promoters by ChIP-PCR.
Lately, codon partition models have been proposed as a viable alternative, mimicking the substitution behaviour of codon models at a low computational cost.
Despite the presence of Drosophila Lamin C aggregates, flies expressing rod domain amino acid substitutions were viable (Table 1) and showed no visible adult phenotypes.
At each position we made predictions with different confidence levels as to whether a number of chosen amino acid substitutions would produce viable or non-viable virus.
Combined mutation of seven of the most conserved residues (scc4 L256L; Y298A; K299didY313A; F324A; K327D; K331D ; scc4 m7 ) did not inactivate Scc4, as strains bearing these substitutions were fully viable and had a plasmid segregation phenotype comparable in strength to that of strains bearing mutations only at positions 324, 327, and 331 (scc4 F331A; K331D; K331D ; scc4 m331.
The other viable opinion towards lead cation (Pb2+) substitution is adaptation of heterovalent (not divalent) cation into the organic-metal-halide crystals.
64 Thus, substitution may not be a viable path to behavior modification if the substitute addiction is not independent of the primary harmful addiction, but the two are associated, for example, cannabis and alcohol.
Although legacy technologies could be replaced with smarter equivalents in other business domains, there are numerous reasons why substitution may not be a viable option in industrial facilities.
