Comparison of the substrates and products of the HpcH, DDG and YfaU aldolases. The substrate for YfaU is unknown, but we have shown that this protein is able to catalyse the cleavage of 4-hydroxy-2-keto-pentanoate (HKP) to pyruvate and acetate. HKP is the substrate of MhpE aldolase from the phenylproprioate pathway of E. coli (Diaz et al., 1988). |
