Updated annotation (from data): galactaro-1,5-lactonase Rationale: Specifically important in carbon source D-Galacturonic Acid monohydrate. This is the second step after D-galacturonate dehydrogenase (PS417_17360) and forms meso-galactarate, which is the substrate of PS417_04210. The substrate is probably the 1,5-lactone, not the 1,4-lactone, given the characterization of the D-galacturonate dehydrogenase from Agrobacterium tumefaciens (PMID:24450804), which is 51% identical to PS417_17360. Original annotation: gluconolactonase Type 1: Protein-coding gene Located on scaffold CP007637, + strand, nucleotides 3,793,415 to 3,794,290 See nucleotide sequence around PS417_17365 or for all of scaffold CP007637
