Yield:-
Reaction Conditions:
with pyridoxal 5'-phosphate;recombinant ω-transaminase from Burkholderia vietnamiensis G4 in aq. phosphate buffer; pH=7.4 at 37; for 0.0833333 h;Enzymatic reaction;enantioselective reaction;
Steps:
2.7. Substrate specificity and enantioselectivity
General procedure: Amino donor specificity was assayed by following the similar procedure of Section 2.5. The amino donor substrates (10 mM) listed in Table 1 reacted with pyruvate (10 mM) as amino acceptor. For racemic amino donor, the concentration was 20 mM. After the reaction, residual pyruvate was analyzed by HPLC according to Section 2.10. Amino acceptor specificity was assayed by following the similar procedure of Section 2.5. The amino acceptor substrates (10 mM) listed in Table 2 reacted with (S)-α-MBA (10 mM) as amino donor. After the reaction, the amount of produced acetophenone was analyzed and the ee values of the produced amines were determined according to Section 2.10.
