Updated annotation (from data): fused D-3-phosphoglycerate dehydrogenase / phosphoserine phosphatase (EC 1.1.1.95; EC 3.1.3.3) Rationale: Important for fitness in defined media, unless serine is added as a nitrogen source. The N-terminal part is distantly related to the phosphoserine phosphatase from Arabidopsis, and no other candidate was found for this step. The C-terminal part is 52% identical to E. coli phosphoglycerate dehydrogenase. Original annotation: Haloacid Dehalogenase superfamily, subfamily IB, phosphoserine phosphatase-like Type 1: Protein-coding gene Located on scaffold Echvi_Contig97.1, - strand, nucleotides 3,317,803 to 3,319,695 See nucleotide sequence around Echvi_2777 or for all of scaffold Echvi_Contig97.1
