2.6.1.18	additional information	synthesis and optical resolution of beta-phenylalanine and other important aromatic beta-amino acids by biotransformation utilizing an omega-transaminase (omega-TA) from Variovorax paradoxus. Design of mutant variants of the omega-TA to gain higher process stability on the basis of predictions calculated by using the FoldX software. Thermostabilization of a nonthermostable S-selective omega-TA by FoldX-guided site-directed mutagenesis. The melting point (Tm) of the best-performing mutant is increased to 59.3°C, an increase of 4.0°C relative to the Tm value of the wild-type enzyme, whereby the mutant fully retains its specific activity	759057
