This involves phrasing an important evolutionary question in two directions, "How well does a more sophisticated model of protein function explain observed evolutionary patterns?" and conversely, "How well do simple evolutionary statistics describing selective constraint (here dN/dS) describe conservation of function or the opportunity for functional shifts in a pathway?".
Finally, we identify several cases of tRNA functional shifts by anticodon point mutations, demonstrating a greater than anticipated role for functional shifts in the evolution of eukaryotic tRNA gene organization.
Ultimately, this modeling framework can be envisioned as leading to the development of new statistical tests for functional shifts in comparative and population genomics.
The type 2 functional divergence (FDII) analysis predicts sites which although conserved in both clusters but are quite distinct in their biochemical features, thereby accounting for functional shifts between the two clusters.
The contrasting disturbance regime from boundaries to inner-fields overflows the potential shifts in functional assemblages both for response and effect traits due to the gradient of landscape heterogeneity.
RME is considered the treatment of choice for functional crossbite because it eliminates the lateral functional mandibular shift, preventing the development of skeletal asymmetry and of muscle function disturbances [56, 59].
These pre-weanling pups were screened for functional mutations (e.g. nonsense mutations, out of frame-shifts mutations, etc).
The report said the 1998 defense review had introduced "a shift in culture and priorities" in the armed forces, substituting "business and financial targets" for "functional values such as safety and airworthiness".
Thus, the shift in pI may be associated with divergence in functional requirements for either rates of digestion, or for functional components of the milk.
After centrifugation, the supernatants are analyzed by MALDI-TOF MS. Specific peaks (mass shifts) for intact and hydrolyzed β-lactams indicate functional presence of β-lactamases.
