Gene info for SM_b20892 in Sinorhizobium meliloti 1021

Updated annotation (from data): 2-dehydro-3-deoxy-L-arabinonate dehydratase (EC 4.2.1.43)
Rationale: Specifically important in carbon source L-Arabinose. Similar to PA2216 from Pseudomonas aeruginosa (see PMC:PMC4038344) and to gguC or araD1 (Atu2345) from Agrobacterium tumefaciens (see PMC: PMC3232879), which also have this activity. In Agrobacterium, this reaction is proposed to be a step in L-arabinose oxidation. (Note that 2-keto-3-deoxy-L-lyxonate and 2-keto-3-deoxy-L-arabinonate are the same compound.)
Original annotation: hypothetical protein
Type 1: Protein-coding gene
Located on scaffold NC_003078, - strand, nucleotides 1,298,943 to 1,299,938
