DeoCDeoC/LacD family aldolase
|SMART accession number:||SM01133|
|Description:||This family includes diverse aldolase enzymes. This family includes the enzyme deoxyribose-phosphate aldolase EC:126.96.36.199, which is involved in nucleotide metabolism. The family also includes a group of related bacterial proteins of unknown function, see examples Q57843 and P76143. The family also includes tagatose 1,6-diphosphate aldolase ( EC:188.8.131.52) is part of the tagatose-6-phosphate pathway of galactose-6-phosphate degradation ((PUBMED:1655695)).|

Deoxyribose 5-phosphate aldolase was purified 41 times from Bacillus cereusinduced by growth on deoxyribonucleosides. The purification procedure includesammonium sulphate fractionation, gel filtration on Sephadex G-100, ion-exchangechromatography on DEAE-Sephacel and preparative electrophoresis on 10%polyacrylamide gel. The enzyme is stable above pH 6.5, but is rapidly inactivatedby sulfhydryl reagents. Being insensitive to EDTA, it may be considered as aClass I aldolase. Among a number of compounds tested (including some carboxylicacids, free and phosphorylated pentoses, nucleotides and nucleosides), none hasbeen found to affect the enzyme activity. The enzyme appears to be dimeric, with a subunit Mr of 23,600. A Km of 4.4 x 10(-4) M was calculated for dRib 5-P.

The nucleotide and deduced amino acid sequences of the lacA and lacB genes of theStaphylococcus aureus lactose operon (lacABCDFEG) are presented. The primarytranslation products are polypeptides of 142 (Mr = 15,425) and 171 (Mr = 18,953) amino acids, respectively. The lacABCD loci were shown to encode enzymes of thetagatose 6-phosphate pathway through both in vitro studies and complementationanalysis in Escherichia coli. A serum aldolase assay, modified to allow detectionof the tagatose 6-phosphate pathway enzymes utilizing galactose 6-phosphate orfructose phosphate analogs as substrate, is described. Expression of both lacAand lacB was required for galactose 6-phosphate isomerase activity. LacC (34 kDa)demonstrated tagatose 6-phosphate kinase activity and was found to sharesignificant homology with LacC from Lactococcus lactis and with both the minor6-phosphofructokinase (PfkB) and 1-phosphofructokinase (FruK) from E. coli.Detection of tagatose 1,6-bisphosphate aldolase activity was dependent onexpression of the 36-kDa protein specified by lacD. The LacD protein is highlyhomologous with LacD of L. lactis. Thus, the lacABCD genes comprise the tagatose 6-phosphate pathway and are cotranscribed with genes lacFEG, which specifyproteins for transport and cleavage of lactose in S. aureus.
