Updated annotation (from data): allantoinase (EC 3.5.2.5); 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU) decarboxylase (EC 4.1.1.97) Rationale: Specific phenotype: utilization of Adenine hydrochloride, Inosine. The N-terminal part is >50% identical to allantoinases. The C-terminal portion is only 36-37% identical to characterized OHCU decarboxylases (i.e., O32141 or Q283N4), but it is the only OHCU decarboxylase domain encoded in the genome. Original annotation: Chitin deacetylase (RefSeq) Type 1: Protein-coding gene Located on scaffold 57145, - strand, nucleotides 3,368,449 to 3,369,861 See nucleotide sequence around Dshi_3204 or for all of scaffold 57145
