| UniProt functional annotation for P32169 | |||
| UniProt code: P32169. |
| Organism: | Escherichia coli (strain K12). | |
| Taxonomy: | Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. | |
| Function: | Catalyzes the reversible cleavage of L-rhamnulose-1-phosphate to dihydroxyacetone phosphate (DHAP) and L-lactaldehyde (PubMed:12962479). Also catalyzes the dephosphorylation of phospho- serine in vitro (PubMed:25848029). {ECO:0000269|PubMed:12962479, ECO:0000269|PubMed:25848029}. | |
| Catalytic activity: | Reaction=L-rhamnulose 1-phosphate = (S)-lactaldehyde + dihydroxyacetone phosphate; Xref=Rhea:RHEA:19689, ChEBI:CHEBI:18041, ChEBI:CHEBI:57642, ChEBI:CHEBI:58313; EC=4.1.2.19; Evidence={ECO:0000269|PubMed:12962479}; | |
| Cofactor: | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000269|PubMed:11976494, ECO:0000269|PubMed:12962479}; Note=Binds 1 zinc ion per subunit. {ECO:0000269|PubMed:11976494, ECO:0000269|PubMed:12962479}; | |
| Biophysicochemical properties: | Kinetic parameters: KM=0.48 mM for L-rhamnulose 1-phosphate (at 37 degrees Celsius) {ECO:0000269|PubMed:12962479}; | |
| Pathway: | Carbohydrate degradation; L-rhamnose degradation; glycerone phosphate from L-rhamnose: step 3/3. | |
| Subunit: | Homotetramer. {ECO:0000269|PubMed:11976494}. | |
| Subcellular location: | Cytoplasm. | |
| Induction: | Induced by L-rhamnose via the RhaR-RhaS regulatory cascade. Binding of the cAMP receptor protein (CRP) is required for full expression. {ECO:0000269|PubMed:10852886, ECO:0000269|PubMed:8230210}. | |
| Similarity: | Belongs to the aldolase class II family. RhaD subfamily. {ECO:0000305}. | |
