Updated annotation (from data): 2-keto-3-deoxy-D-arabino-heptulosonate-7-phosphate synthase / chorismate mutase (EC 2.5.1.54; EC 5.4.99.5) Rationale: Important for fitness in most defined media. The N-terminal DHAP region is only 33% identical to the Pyrococcus enzyme (Q8U0A9) but the active site and substrate-binding residues are conserved. The C-terminal chorismate mutase region is diverged but hits PF01817 and no other chorismate mutase was found in the genome. Original annotation: 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthase Type 1: Protein-coding gene Located on scaffold Echvi_Contig97.1, + strand, nucleotides 119,948 to 121,051 See nucleotide sequence around Echvi_0120 or for all of scaffold Echvi_Contig97.1
