PigD catalyzes 1,2-additions using 2-oxoacids as donor substrates and aldehydes as acceptors. In the case of ketones as acceptors PigD catalyzes the 1,4-addition. Although pyruvate is the preferred donor substrate, 2-oxobutanoate is also employed using (E)-4-(4-chlorophenyl)-but-3-en-2-one as an acceptor
