Functional characterization of PLP fold type IV transaminase with a mixed type of activity from Haliangium ochraceum

Pyridoxal-5′-phosphate (PLP)-dependent transaminases are industrially important enzymes catalyzing the stereoselective amination of ketones and keto acids. Transaminases of PLP fold type IV are characterized by (R)- or (S)-stereoselective transfer of amino groups, depending on the substrate profile of the enzyme. PLP fold type IV transaminases include branched-chain amino acid transaminases (BCATs), D-amino acid transaminases and...
