    4.2.1.90 | malfunction |
a double deletion of lraC and lraA in Aspergillus niger results in a strain that exhibits no L-rhamnose dehydrogenase activity and cannot consume or grow on L-rhamnose. Deletion of the clustered genes lraA, lraB or lraC causes a reduction in expression level of the other genes of the L-rhamnose pathway, rhtA is not expressed in the DELTAlraC and DELATrhaR mutants. Strongly reduced expression levels of lraA, lraB, rhaR, rglB, rgxA and rgaeA are observed in the DELTAlraC mutant upon the 2 h transfer to L-rhamnonate compared to the reference strain |

| 4.2.1.90 | metabolism |
L-rhamnonate dehydratase (LRA3) converts L-rhamnonate to 2-dehydro-3-deoxy-L-rhamnonate (L-KDR), catalyzing the third step of the non-phosphorylative pathway in Schefferomyces stipitis. The inducer of RhaR is beyond L-rhamnonate dehydratase (LraC) and is likely to be the 2-keto-3-L-deoxyrhamnonate |

| 4.2.1.90 | metabolism |
L-rhamnose is oxidised to L-rhamnonate which is then reacting with a dehydratase. The resulting 3,6-dideoxy-L-erythro-hexulosonic acid (2-dehydro-3-deoxy rhamnonate) is subsequently split by and aldolase to pyruvate and L-lactaldehyde |
