Especially when it comes to the creation of variant libraries, fast and reliable detection methods to identify the best catalyst are essential.
Phenotype and sequence data for a million people will allow the discovery of more risk and trait variants and the creation of multiple-variant profiles that can be used for prediction.
As a first version, a set of fourteen easy-to-use Maple commands is introduced for symbolic creation of (improved variants of Poincaré's) normal forms as well as their associated normalizing transformations.
The bacterial expression system for the C-terminal fragment of GalMBP allows easy production of large quantities of trimeric protein with clusters of binding sites and will facilitate creation of further variants with modified selectivity for different sets of glycans.
A synthetic biology approach to protein engineering has been enabled by recent advances in gene synthesis technology [ 23- 26] that permit cost-effective synthesis of individually specified gene sequences instead of relying on creation of libraries of variant sequences [ 27, 28].
Plates were incubated for 14 h at 37°C prior to picking individual colonies (in the case of site-directed mutagenesis for creation of blue shifted variants) or fluorescence-based library screening for red shifted variants.
A brief background of the motivation behind the creation of the above variants is provided.
Creation of new toxin variants with higher membrane permeabilizing activity has been considered as an important biotechnological perspective [ 4].
Most probably, alternative splicing did not lead to the creation of the these variants because alternative splicing is uncommon in ciliates [ 67].
Experimentally, directed evolution relies upon iterative rounds of creation of novel protein variants by introduction of random mutations into the target gene and selection of individuals with desirable characteristics.
Thus, protein improvement is likely to involve the creation of increasingly 'smart' variant libraries over larger parts of the protein.
