Most often, promoter choice and codon usage were hypothesised to be the main reason for expression failures.
Potential needs a catalyst, a reason for expression.
SNP-mediated mutation in promoter motifs might be regarded as a reason for expression divergence (fig. 8 B).
One specific reason for expression of multiple amino acid carriers may be that, if only one single carrier was present, a large excess of a single amino acid would prevent uptake of all other amino acids by competitive inhibition.
The reasons for failed expression included insoluble production as inclusion bodies or toxicity resulting in death of the expression cultures (Additional file 1: Table S1 S3).
The cheap, sustaining and healthy bean – there are sound nutritional reasons for the expression "full of beans" – is ideal fare for the demanding days of winter.
There could be two possible reasons for transcripts expression in psy1r-independent response.
Although more accumulated evidences are required, reduction of pVHL or Siah-1 would be one of the reasons for elevated expression of PAK1 in human cancer, which may lead to disruption of Smad4-induced cell death.
In this version, the relevant norms are not supposed to provide guidance, justification, or reasons for using expressions one way or another – according to her, it is precisely these requirements that generate vulnerability to quussing.
