Updated annotation (from data): D-arabinoate dehydratase (EC 4.2.1.5); also involved in L-fucose catabolism Rationale: Specifically important in carbon source D-Arabinose; carbon source L-Fucose. SMc02776 is 36% identical to D-galactarate dehydratase (garD) from E. coli, which is a similar reaction. The product (2-dehydro-3-deoxy-D-arabinonate) is consumed by SMa0247. The role of SMc02776 role in L-fucose catabolism is unclear because two other dehydratases (SM_b21107 and SM_b21110) are also required but the pathway requires only one dehydratase reaction (PMID:17144652). Probably two of these dehydratases act together (with one of them in reverse) to switch the stereochemistry of a chiral center.
