Categorisation of sugar acid dehydratases in Aspergillus niger
چکیده انگلیسی
In the genome of Aspergillus niger five genes were identified coding for proteins with homologies to sugar acid dehydratases. The open reading frames were expressed in Saccharomyces cerevisiae and the activities tested with a library of sugar acids. Four genes were identified to code for proteins with activities with sugar acids: an l-galactonate dehydratase (gaaB), two d-galactonate dehydratases (dgdA, dgdB) and an l-rhamnonate dehydratase (lraC). The specificities of the proteins were characterised. The l-galactonate dehydratase had highest activity with l-fuconate, however it is unclear whether the enzyme is involved in l-fuconate catabolism. None of the proteins showed activity with galactaric acid or galactarolactone.
