| + | [https://www.uniprot.org/uniprot/DGOA_ECOLI DGOA_ECOLI] Involved in the degradation of galactose via the DeLey-Doudoroff pathway. Catalyzes the reversible, stereospecific retro-aldol cleavage of 2-keto-3-deoxy-6-phosphogalactonate (KDPGal) to pyruvate and D-glyceraldehyde-3-phosphate. In the synthetic direction, it catalyzes the addition of pyruvate to electrophilic aldehydes with re-facial selectivity. It can use a limited number of aldehyde substrates, including D-glyceraldehyde-3-phosphate (natural substrate), D-glyceraldehyde, glycolaldehyde, 2-pyridinecarboxaldehyde, D-ribose, D-erythrose and D-threose. It efficiently catalyzes aldol addition only using pyruvate as the nucleophilic component and accepts both stereochemical configurations at C2 of the electrophile.<ref>PMID:324806</ref> <ref>PMID:17981470</ref> [https://www.uniprot.org/uniprot/FKBA_ECOLI FKBA_ECOLI] PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. | ||
