construction of a DELTAlraC knockout mutant from strain CBS 141257, gene deletion and transcriptomic analysis is performed to elucidate the function of LraC, protoplast-mediated transformations of Aspergillus niger. Deletion of genes lraA, lraB or lraC causes a reduction in expression level of the other genes of the L-rhamnose pathway. 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. But none of the deletions of genes lraA, lraB or lraC results in accumulation of the inducer of the pathway regulator (RhaR) |
