For the fourth rescued growth phenotype (glutamine-fructose-6-phosphate transaminase, BT_0554), no information could be found for B. thetaiotaomicron, but in E. coli, the gene knockout causes a glucosamine requirement.
Another example are the carAB genes: even though these genes are not characterized in C. glutamicum they are well known to cause a double requirement for both arginine and uracil in E. coli since they encode for the subunits of a protein that provides the essential carbamoylphosphate for arginine and pyrimidine biosynthesis [ 39].
Not only are these requirements causing a lot of stress, she says that the materials for the tests are also very expensive.
To counteract this process, the monetary authorities would raise interest rates and stiffen credit requirements, causing a fall in prices, income, and employment; this in turn led to a reduction in imports and an expansion of exports, thus improving the balance of payments.
"To say that the GCSE requirement is causing a recruitment crisis is not an exaggeration," he added.
For most plants, the accumulation of biomass accompanying shoot elongation causes an increased requirement for support (Rowe and Speck, 2004).
The gradual degeneration of the proto-Y chromosome causes an increasing requirement to equalize gene expression between a single X (in males) and two X-chromosomes (in females) and to balance this level of expression with that of the two sets of autosomal chromosomes (Oliver 2007; Vicoso and Bachtrog 2009; Prestel et al. 2010a; Stenberg and Larsson 2011).
Still, Kenneth Branagh has just proved that it's possible to overcome deficiencies caused by a requirement to work extensively in CGI and still end up making a good film.
One inconsistency was caused by a requirement for a cofactor that could not be modeled.
We considered whether the ability of the JAK inhibitor tofacitinib to decrease Myc expression in T cells could be caused by a requirement of JAK activity for system L amino acid uptake and protein synthesis in activated T cells.
